This document summarizes the major groups within the plant kingdom. It describes:
1) Non-vascular plants (bryophytes) including liverworts, hornworts, and mosses which were the earliest land plants but lacked tissues for transporting water and nutrients.
2) Vascular plants (tracheophytes) including lycophytes, horsetails, ferns and their allies which were the first to develop tissues allowing them to grow larger.
3) Seed plants (spermatophytes) including conifers, cycads, ginkgo, gnetae and flowering plants which advanced further with pollen and seeds, allowing for fertilization over long distances
The document provides an overview of plant evolution and diversity. It begins with the earliest aquatic algae and charophytes, transitions to the first land plants like Cooksonia, and traces the major lineages including bryophytes, lycophytes, ferns, gymnosperms like cycads and conifers, and finally flowering plants. Key adaptations that facilitated the colonization of land are discussed. Various terms related to plant reproduction and life cycles are also defined.
1) Green plants include land plants and green algae. Land plants evolved from a group of freshwater charophyte algae and have multicellular haploid and diploid phases with protected embryos.
2) Plants have a life cycle with alternation between a multicellular diploid sporophyte generation that produces haploid spores and a multicellular haploid gametophyte generation.
3) Major groups of land plants include bryophytes (non-vascular), lycophytes and pterophytes (vascular non-seed plants), and seed plants including gymnosperms and flowering plants.
This document discusses the evolution and diversity of vascular plants. It defines key characteristics of tracheophytes, including vascular tissue, supportive tissue, roots and shoots. It describes lignin and secondary cell walls. It discusses the alternation of generations life cycle and key plant tissues/structures like xylem, phloem, sclerenchyma and fibers. The document outlines the major groups of vascular plants including rhyniophytes, lycopodiophytes, and euphyllophytes. It provides examples of extant lycophytes like club mosses, spike mosses and quillworts.
Kingdom Plantae includes eukaryotic, multicellular organisms that are autotrophic, producing their own food through photosynthesis. They have cell walls made of cellulose and lack mobility. Plants reproduce both sexually through male and female gametes and asexually through structures like spores. They are divided into four main groups - mosses, ferns, gymnosperms and angiosperms - based on the presence of vascular tissue and seeds. Angiosperms make up the majority of plant species and their success is attributed to adaptations like specialized structures for pollination, protected seeds, and fruit aiding in seed dispersal.

Bryophytes likely represent three separate evolutionary lineages known as mosses, liverworts, and hornworts. Each moss sporophyte consists of a foot, stalk, and capsule that extends from the gametophyte plant and is somewhat parasitic, though able to produce some of its own food. Mosses are estimated to include between 10,000 to 15,000 species classified into four major groups: Sphagnopsida, Andreaeopsida, Polytrichopsida, and Bryopsida. Higher-level moss classification remains unresolved.
This document provides information on the classification of plants. It discusses the key characteristics of plants, including that they are multicellular organisms that can perform photosynthesis. Plants are classified into two main groups: non-vascular and vascular plants.

Polypodiophyta are vascular plants that reproduce via spores and range in size from less than 1 cm to 25 m tall tree ferns. Their leaves, called fronds, are megaphylls that are typically divided into smaller segments and require external water for reproduction. Spores are released and grow into small, flat gametophytes that bear archegonia and antheridia for sexual reproduction. A zygote develops into an independent sporophyte as the gametophyte dies off. Ferns were abundant as tree ferns during the Carboniferous period 320-250 million years ago. Some modern uses include using fern fronds in floral arrangements.
I give this slide for your learning from the pictures. I put many pictures in the slide. It is easy way to learn from this slide. This slide tells us about the plants and their classification . It is copyright from the textbook of 9th standard. This is biology.
Tracheophytes, or vascular plants, have specialized tissues called xylem and phloem that allow them to transport water and nutrients throughout the plant. They are divided into three classes: ferns, gymnosperms, and angiosperms. Ferns have vascular bundles and reproduce via spores, while gymnosperms like conifers and cycads reproduce using naked seeds. Angiosperms, which include flowering plants, have fruits containing seeds and complex vascular tissue.
The life cycle of ferns involves alternation of generations between a haploid gametophyte and a diploid sporophyte. The sporophyte produces spores through meiosis in structures called sori located on the underside of fern leaves. These spores develop into multicellular gametophytes that produce egg and sperm cells through mitosis. Fertilization of an egg and sperm results in a zygote that grows into a new diploid sporophyte, completing the life cycle.
This document provides an overview of plant and animal biology. It discusses the study of biology and key areas of botany and zoology. It also summarizes classifications of organisms from the three domain system to the tree of life. Major groups of plants like bryophytes, seedless vascular plants, gymnosperms and angiosperms are described.

This document provides an overview of plant classification and describes the main plant groups. It discusses the four main classifications of plants: mosses and liverworts (Bryophyta), ferns (Pteridophyta), conifers (Gymnosperms), and flowering plants (Angiosperms). For each group, it outlines key distinguishing characteristics, examples, and life cycles. It also covers scientific naming conventions and describes several important families of flowering plants.
Diversity is recognizing and appreciating the unique characteristics of individuals in a way that promotes achievement for both individuals and groups. Classification of plants depends on whether they have differentiated tissues for transporting water and other substances. Thallophyta include algae, fungi and lichens which may be unicellular or multicellular but lack distinct tissues. Bryophyta like mosses lack vascular tissues. Pteridophyta like ferns have sporophytes that are well developed with roots, stems and leaves. Gymnosperms are seed plants with unconcealed seeds borne in cones. Angiosperms are flowering plants with seeds contained within fruits that develop from ovaries.
1. Selaginella is a heterosporous plant that produces megaspores and microspores. The spores develop into male and female gametophytes within their spore walls.
2. Microspores develop into male gametophytes containing antherozoids for fertilization. Megaspores develop into female gametophytes containing archegonia.
3. Fertilization occurs when antherozoids enter the archegonia through openings in the neck canal cells. This leads to the development of a diploid sporophyte within the megaspore.

This document describes characteristics of bryophytes and their importance. It discusses:
1. Bryophytes include mosses, liverworts and hornworts which reproduce via alternation of generations between a haploid gametophyte and diploid sporophyte generation.
2. They play important roles through peat formation, use as fuel and horticultural additives, and in providing seed beds, food and shelter.
3. Bryophytes also serve as indicators of environmental conditions like soil pH and acid rain, and have some medicinal uses.
Bryophytes are the oldest land plants that have been around for over 400 million years. They are non-vascular plants that do not have true roots but have rhizoids. There are around 2,000 species of bryophytes divided into three groups: mosses, liverworts, and hornworts. Mosses are typically small, soft plants that grow in moist areas. Liverworts are also small flowerless plants that can cover patches of ground and produce spores in capsules. Hornworts have spores produced in horn-like capsules and there are only around 100 species.
This document summarizes key aspects of angiosperms including their evolution, life cycle, and the field of systematic botany. It discusses how angiosperms evolved diversified forms and efficient reproduction mechanisms. Their life cycle involves an alternation between a dominant sporophyte generation and a reduced parasitic gametophyte generation. Systematic botany aims to classify and name all plant species based on their morphology and relationships, which is important for fields like agriculture, forestry, and ecology.
Affinities of bryophytes with algae and pteridophytesvaishalidandge3
Bryophytes share several similarities with both algae and pteridophytes. With algae, they have a simple plant body, are autotrophic, have a dominant gametophytic phase, lack roots and vascular tissue, have similar pigments, and have flagellated antherozoids. Bryophytes also resemble algae in producing filamentous protonema and having pyrenoids in their plastids. Bryophytes resemble pteridophytes in being terrestrial, having primitive sporophytes, reproducing sexually through oogamy, having flagellated antherozoids where water is needed for fertilization, retaining the zygote, forming embryos from the zygote,

3. The document provides detailed information on the structure and development of vascular bundles, vascular cambium, xylem differentiation, leaf traces, and classification of stele types in plant stems.
Nonvascular plants lack true roots, stems, and leaves due to the absence of vascular tissue. They are called thallophytes and include mosses, liverworts, and hornworts. They must live in moist environments because they lack internal structures for transporting water and nutrients and generally only grow 1-2 cm tall. Vascular plants have specialized tissues for transport and include both spore-bearing plants like ferns and seed-bearing plants like gymnosperms and angiosperms. Gymnosperms produce naked seeds enclosed in cones while angiosperms produce seeds enclosed within flowers in an ovary.

Botany Bryophytes notes for 1st semester.pptxSPChaithanya
Bryophytes are non-vascular land plants that are considered the first plants to colonize land. They include mosses, hornworts, and liverworts. Bryophytes lack true roots, leaves, and vascular tissues. They have two generations in their life cycle - the haploid gametophyte generation, which produces gametes, and the diploid sporophyte generation, which produces spores. Fertilization of an egg cell by sperm occurs within archegonia on the gametophyte, forming a zygote that develops into the sporophyte. The sporophyte produces haploid spores via meiosis within capsules. There are two hypotheses for the evolutionary origin of b
The document summarizes four main plant phyla: Bryophyta (mosses), Pteridophyta (ferns), Gymnosperms (conifers), and Angiosperms (flowering plants). It provides details on the characteristics and life cycles of mosses, ferns, and conifers. Mosses are non-vascular plants that rely on moisture for transport and help prevent erosion. Ferns have vascular tissue but reproduce via spores. Conifers reproduce via naked seeds in cones and have needle-like or scale-like leaves. The document then states it will provide details on important angiosperm families.
This document provides a summary of key points from Chapter 24 of Biology 102 on the evolution and diversity of plants. It discusses how plants evolved from green algae over 500 million years ago, and the characteristics that distinguish them as multicellular photosynthetic organisms adapted to life on land, such as cell walls containing cellulose. It also summarizes the alternation of generations life cycle in plants, the adaptations that allowed plants to colonize land, and an overview of the characteristics and reproduction of nonvascular and vascular plants including seedless plants, ferns, gymnosperms, and angiosperms.
The document provides information on the classification of living organisms into five kingdoms - Monera, Protista, Fungi, Plantae, and Animalia. It then describes some of the main groups within the plant and animal kingdoms. The plant kingdom is divided into cryptogams and phanerogams. The animal kingdom includes porifera, coelenterata, nematoda, annelida, arthropoda, mollusca, echinodermata, protochordata, and vertebrata. Examples are given for important groups like fungi, bryophytes, pteridophytes, gymnosperms, angiosperms, and the five classes of vertebrates.
Pteridophytes are vascular plants that reproduce via spores rather than seeds. They include ferns, horsetails, and lycophytes. Pteridophytes have well-differentiated roots, stems, and leaves. They reproduce through spores produced in sporangia. Ferns are the largest group of pteridophytes and can be homosporous or heterosporous.
This document provides a summary of the flora and fauna found along the Dodder River. It lists 5 types of plants found along the river: Bryophytes, algae, Crocosmia, Japanese knotweed, and Impatiens glandulifera. It also lists 5 types of animals found near the river: mallard, grey heron, dipper, coot, and moorhen. The document then provides 1-2 paragraphs describing each of these types of flora and fauna.
The document provides a detailed overview of the hierarchical classification system used to classify living organisms. It describes the five kingdom system including Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is then broken down into smaller subgroups like phylum, class, order, family, genus and species. Examples are provided for important subgroups in each kingdom like bacteria, fungi, ferns, flowering plants, sponges, jellyfish, worms, insects, fish and mammals.
This document provides classifications for various types of animals and plants. It divides animals into several phyla based on their characteristics, including chordates, molluscs, echinoderms, platyhelminths, nematodes, cnidarians, annelids, protozoa, arthropods, poriferans, and rotifers. It also describes key characteristics of classes within these phyla like reptiles, birds, mammals, fish, amphibians. Similarly, it categorizes plants into seedless vascular plants, non-vascular plants, and seeded vascular plants, outlining example types like ferns, horsetails, mosses, cycads, conifers, and flowering plants.
The document provides information about different types of plants, including their structures, life cycles, and evolutionary relationships. It discusses bryophytes like mosses which were some of the earliest plants and do not have vascular tissue. It then covers seedless vascular plants including ferns, club mosses, and horsetails, which have specialized tissues to transport water and nutrients. The life cycles of ferns are described in detail, involving alternation between haploid gametophyte and diploid sporophyte generations.
The document provides a detailed overview of the classification of living organisms across five kingdoms - Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is further divided into smaller sub-groups at various levels from phylum down to species. Key points include that Monera contains prokaryotes, Protista and Fungi contain eukaryotes, and Plantae and Animalia contain multicellular eukaryotes. The document also describes the five-kingdom system of classification and provides examples of representative groups within each kingdom.
The document summarizes the evolution of plants from aquatic to terrestrial environments. Early plant ancestors were green algae that lived in water. They developed adaptations like vascular tissue to transport water and nutrients on land. These included roots, stems, leaves, and a waxy cuticle. Land plants diversified into spore-producing plants like ferns and seed-producing plants like flowering plants. All plants undergo an alternation of generations between haploid and diploid forms.
This document summarizes key points about plants from Chapter 3, including:
1) Plants are important for ecosystem services, fuels/fibers, and other uses. They evolved from green algae in water and later colonized land.
2) There are four major plant groups: non-vascular plants, seedless vascular plants, gymnosperms, and angiosperms.
3) Plants generally alternate between a sporophyte generation with 2n chromosomes and a gametophyte with n chromosomes.
This document summarizes the classification of plants. It discusses how plants are divided into kingdoms, divisions, and phyla based on characteristics like their vascular systems, how they reproduce, and their size. The major divisions covered are non-vascular plants like mosses, vascular plants that reproduce via spores like ferns, and vascular plants that reproduce via seeds like conifers. Over 260,000 identified plant species are sorted among these groups.
The document describes the three divisions of bryophytes - liverworts, mosses, and hornworts. It outlines their key characteristics such as lacking true roots, stems and vascular tissue. Liverworts have a flattened thallus structure or leafy appearance. Mosses have a leafy body and reproduce asexually through budding. Hornworts are distinguished by their horn-like sporophytes. All bryophytes reproduce both sexually and asexually and play an important role as some of the earliest land plants.
This document provides an overview of the five-kingdom classification system used to categorize different types of living organisms, with a focus on the plant kingdom. The key characteristics used to classify organisms are whether their cells are prokaryotic or eukaryotic, unicellular or multicellular, and whether they have cell walls or can perform photosynthesis. Within the plant kingdom, the main subdivisions discussed are thallophyta (algae and fungi), bryophyta (mosses and liverworts), pteridophyta (ferns), gymnosperms (conifers and cycads), and angiosperms (flowering plants). Examples and brief descriptions are provided for each group.
This document summarizes the evolution and diversification of early tracheophytes. It discusses:
1) The first tracheophytes were rhyniophytes that lacked leaves and roots and consisted of dichotomously branching stems. They gave rise to two major lineages - lycophytes and monilophytes.
2) Lycophytes include club mosses and quillworts. They have leaves, roots, and laterally attached sporangia. Selaginella is heterosporous while Lycopodium is homosporous.
3) Monilophytes include whisk ferns, horsetails, marattialean ferns, and true ferns.
This document summarizes the classification of plants into five major groups - Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms. It describes the key characteristics of each group, such as their body structure, reproductive processes, and ability to conduct water and nutrients. Examples are provided for each group, like algae for Thallophyta, mosses for Bryophyta, and flowering plants like roses and potatoes for Angiosperms. The Angiosperms group is further divided into monocots and dicots based on the number of cotyledons in their seeds.
Bryophytes are a division of nonvascular plants that include mosses, liverworts, and hornworts. They were some of the earliest land plants, emerging around 485 million years ago. Bryophytes grow in habitats where water is periodically available, such as forest floors, tree trunks, and damp soil. They reproduce through an alternation of generations, where the dominant gametophyte generation produces sex organs and a dependent sporophyte generation that produces spores and fertilizes the eggs to form diploid zygotes. Bryophytes play important ecological roles in soil formation, moisture retention, and nutrient recycling in forests.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Plant Phylogenetic Description
1. Diversity of Life
The Kingdom of Plants
King Chloroplast
Major Groups: Extant phyla within the kingdom Plantae
2. A. Non-vascular plants (bryophytes)
1. Marchantiophyta - liverworts
2. Anthocerotophyta- hornworts
3. Bryophyta - mosses
B. Vascular plants (tracheophytes)
1. Lycopodiophyta - clubmosses
2. Equisetophyta - horsetails
3. Pteridophyta - "true" ferns
4. Psilotophyta - whisk ferns
5. Ophioglossophyta - adderstongues
6. Seed plants (spermatophytes)
a) Pinophyta - conifers
b) Cycadophyta - cycads
c) Ginkgophyta–ginkgo
d) Gnetophyta - gnetae
e) Magnoliophyta - flowering plants
Mosses and their allies,liverworts and hornworts, are the oldest land plants in the world. These
plants are all non-vascular, meaning they have no tissue for transporting water and nutrient
thought the cell. Their spoors must be transported and united into diploid cells by an outside
water source flowing through the plant. Nutrients must be distributed the same way, with each
piece of the plant relying on the luck to have nutrients be washed its way. Non vascular plants
are thus limited to a small size, as each cell can only obtain nutrition a direct neighbor cell
diffusing some or by water flowing over it. Because of this, the non-vascular plants are only able
to colonize places where water flows regularly.
3. Marchantiophytais the name of the liverwort phylum. These are possibly the oldest land
plants in the world, and, together with hornworts, are the most primitive plants to be found today.
There are two classes of liverworts, Jungermanniidea(leafy) andMarchantiopsida(leaf-like). The
leafy liverworts in the first generation (gametophyte) look very like mosses. Leaf-like liverworts
in the first generation look like plump leaves. The spoors, rather than being produced on the end
of a thin stalk like leafy liverworts, are produced on the underside of an umbrella shape on the
end of a thick stalk (thecarpocephalum).
Anthocerotophyta is the name of the hornwort phylum.These may also be the oldest land
plants in the world. There is only one class in the phylum Anthocerotophyta, it is Anthocerotae
which has but one order, Anthocerotales .Hornwort cells are notable because, unlike other land
plants, their cells contain only one large chloroplast each. Hornwort sporophyte generations
manifest themselves inside, rather than on, the green central stalk, which splits open upon
maturity to release the spoors.
Bryophyta is the name of the moss phylum. While hornworts and liverworts are only
distantly related to all other plants, mosses are probably the ancestors of most land plants.
Though still primitive, being non vascular, mosses are less primitive and more diverse than either
liverworts or hornworts and have a central support on their leaves. This midrib may be the
predecessor to stalks in vascular plants. The sporophyte of a moss is a long stalk with a capsule
on the end. The sporophyte grows parasitically on the gamete generation until it reaches
maturity, upon which it splits open and releases the spoors. The stalk may remain for some time
after that. There are three classes in the Moss phylum: Peat Mosses (Sphagnopsida), Granite
Mosses (Andreaopsida), and true mosses (Bryopsidia). Peat mosses are often found in bogs and
have historically been burned for fuel.
Ferns and their allies (club mosses, horsetails, whip ferns, and adderstounges) are the next
generation of plants, and the next line of attack against rocks. They are the first vascular plants,
meaning they have developed specialized tissues for water and nutrition transport (roots, stems,
leaves). They also develop firm tissues for structural support. All of these together allow early
vascular plants to reach hithertounknownheights; literally, as some can grow to the sizes of small
trees, and so monopolize more sunlight. Roots allow the plant to survive when water is not
running directly over all parts of the plant. If one root is in a sufficiently wet place, it can,
distribute the water to all other parts of the plant. However, the spoors of ferns and their allies
rely on water in the same way moss spoors do, requiring the luck for water to run in exactly the
right place at the right time for fertilization to occur. Because of this, plants were still limited to
wet places through which water regularly ran.
4. Psilotophyta is the name of the whisk fern phylum. Whisk ferns are notable because,
although they contain vascular stems, they lack roots. Instead, their stems are simply buried in
the ground. Whisk ferns are dichotomous, meaning they branch off in pairs. Taxonomy
accidentally mirroring physiology, there are two genera (only one class, order, and family)
within the phylum, Psilotum andTmesipteris. Psilotumis the more primitive of the two, and
perhaps the most primitive of vascular plants to be seen today, because it lacks leaves as well as
roots, instead having proto-leaf extensions of the stem called enations. However, Tmesipteris’s
gametophyte generation has no vascular tissue, so Psilotum appears more advanced until the
sporophyte stage.
Lycopoidiophyta is the club moss phylum. It is the oldest living phylum of vascular
plants, having fossils dating to 420 Megayears ago. This phylum is notable because although it
does not contain true leaves, but photosynthetic elongations of the stem called enations, each
enations has a vascular trace (capillary). In this way, the club moss phylum links the primitive
whisk ferns and true ferns as the vascular system extends and develops, the leaf being the next
logical step from vascularized enations. In addition to paving the way for leaves, these plants
assist human society in a financial way, as many of these plants fossilized into what are now coal
mines. Their spores are used in fireworks.
Equisetophyta is the name of the Horse Tail Phylum. The horse tail phylum evolved
aporximately 400 million years ago, and became very important by the 300-250 Megayear ago
mark. Horsetails are significant because they demonstrate the gradual evolution of leaves.
Horsetail leaves are true leaves, with true vascular systems, but the leaves are not yet evolved to
be fully and gracefully extended on the plant, leaving the plant with small, but true leaves,
thereby linking the morphic chain from moss to fern completely. Species in this genus such as
the E. arvensecan regrow from seemingly nothing, having been dug up by the roots, because
horsetail gametophytes are buried so far into the ground. In the Carboniferous period, horsetails
were big, in two ways, once they covered almost all the world but Australia, and two and they
could grow up to 30 meters (90 ft) tall. Since the rise of seed plants, however, horsetails have
suffered. There is now only one continuing class of horsetail left , Equisetopsida, in it a one
extant order, Equisetales , in that a lone living family, Equisetaceae, which shelters the sole
surviving genus, Equisetum , which contains a mere fifteen species. Horsetails are therefore,
considered living fossils, but that doesn’t stop them getting weeded out of gardens across the old
world.
Pteridophyta is the name of the fern phylum. Ferns first appeared 350-250 Megayears
ago.Since then ferns have evolved into a total of 20,000 species, divided into four classes:
Psilotopsida, Equisetopsida, Marattiopsida, andPolypodiopsida, the former being the
stereotypical fern most people associate with the name. These thousands of species have been
busy evolving into many specialized nieces, from banks of rainforest ponds to sheer, dry desert
rocks, ferns can be found, despite early plants’ noted difficulties in that area. The gametophyte
stage of the fern is very hard to find, for it is just a small heart-shaped green leaflet. It is the
sporophyte that one imagines when they hear the word “fern.” Fern sporophytes sprout up into
fronds (fern-shaped leaves) that shelter spores on their underside and can grow as tall as trees.
5. Ophioglossophyta is the name of the adderstongue, moonwort, and grape-fern phylum.
Until recently, adderstongue were thought to be ferns, but gradually biologists have realized that
adderstongue and allies are individual. However, dispute continues. While the currently winning
viewpoint gives adderstongueand allies their own phylum, there is another scheme which groups
adderstounges, whisk fern, and horsetails as classes in a single phylum, Archeophyta. This
phylum, unlike ferns, has underground gametophytes and fleshy roots. In some species it can
take as long as 20 years for a gametophyte to send up a sporophyte, and when that occurs, it is
usually a single spore-dusted stalkwhich sprouts a single leaf or frond, if any. There are two
families within this phylum, Ophioglossaceae, and the moonworts and grape-ferns,
Botrychiaceae. However, it should be noted that some biologists place moonworts with
Ophioglossacea rather than Botrychiaceae. Adderstongue have more chromosomes than any
other known plant.
Gymnosperms (pines, conifers, and allies) are the third category of plants. As ferns and the allies
before them, gymnosperms are vascular, but they have advanced an additional giant leap:
gymnosperms have pollen, and produce seeds. Pollen allows fertilization to take place at great
distance, via the wind, rather than directly running water. Seeds are the resultant embryos, but in
an egg-like structure, rather than unprotected or nourished. Seeds store food for the embryo, and
surround it with a hard case. This enables offspring to remain dormant until conditions are right,
surviving off nutrients within the seeduntil, for example, the next rain. This greatly improves
offspring survival rate. The name “gymnosperm” means “naked seed” referring to the fact that
they do not case their ova in ovaries, but instead merely house their ova in cones. Concurrently,
their pollen is not displayed in flowers, but simply thrown to the winds (it is because of this that
pine pollen turns all Georgia yellow each spring.) To further legitimize the naked metaphor, the
fertilized embryos (seeds) of gymnosperms are not set in fruits, but also thrown to the winds.
Gymnosperms have four existent phyla, Pinophyta, Cycadophyta, Ginkgophyta, and Gnetophyta.
Cycadophyta is the name of the cycad phylum. Though now rare, this was once a
dominant phylum during the Jurassic. For this reason cycads are thought of as living fossils.
They are evergreen and similar in looks to a palm tree, although true palms are angiosperms.
However, the two groups share distribution somewhat, as cycads live in a wide range of
equatorial environments, cycads having been found in sand, dirt and on rocks, in semi-arid and
tropical regions about the equator. This is made possible by the small phylum being well adapted
to heat and sunlight, as well as partially adapted to dry conditions, the partial adaption giving
6. flexibility. All cycads have a symbiotic relationship with cyanobacteria, blue - green algae which
lives with the cycads roots, nitrogen fixes the soil, and imparts a toxic quality to cycad seeds.
Cycads, like ginkgoes, are either male or female, but never both. Cycad fossils have been found
that are 280 megayears old, and there are possible (but disputed) cycad fossils dated as far back
as 320 megayears ago.
The ginkgo phylum has only one living species left in it, Ginkgo biloba. Fossils of this
species, or one very like it, can be found as early as the Jurassic, making this tree one of the most
well known examples of living fossils today. Ginkgo trees are either male or female, but never
both, as many angiosperms are. They grow aerial roots very slowly some taking as long as 100
years, to no known purpose.
Pinophyta(until recently, Coniferophyta) is the largest phylum of gymnosperms. So much
so that it used to be considered the only phylum of gymnosperms.They were very successful at
this, it appears, for while there are few species of conifers, they can be found on most of the
world (see map below). As for the classification within Pinophyta, it is currently in dispute.
Pinopsidia is the only complete class. The other classes are cited as no longer existent, or as
merely divisions. Pinopsidiahas simple leaves and secondary root and stem growth. This class
includes pines, firs, spruces, redwoods, yews, ect. As those familiar with plants can ascertain
from the examples given, they cover a wide range, and are most important in boreal forrests of
the north.
Conifer’s distribution
The phylum Gnetophyta is the most advanced of the gymnosperms. It is significant
because, unlike other gymnosperms, it has an angiosperm’s woody vascular bundles. For this
reason, biologists suspect it may be the “missing link” between gymnosperms and flowering
plants. This phylum has three orders in it Gnetales, Welwitschiales, and Ephedrales. All together
there are only six species in the phylum Gnetophyta.
7. Magnoliophyta (once called Anthophyta) is the flowering plants. This is the only phylum of
angiosperms, which means “enclosed fruit”. The flowering plants are the largest plant phylum in
terms of number of species by a great deal. Angiosperms encase their seeds in fruit, and their ova
are housed in ovaries, thus this phylum is protecting their offspring wherever possible. Fruits
often store sugars in order to attract animals into eating them. After a fruit is eaten, the seeds
(evolutionarily packaged to be indigestible) will pass through the digestive system of the animal
and be deposited elsewhere with a pile of handy fertilizer. This process increases the rate of
reproductive spread and success. Flowers are specialized leaves which all angiosperms have,
whether they are as conspicuous as a venus flytrap or as easy to overlook as the flowers of an
oak. Flowers often have sugary nectar for the purpose of attracting insects. These insects, while
eating the nectar, will get pollen (male plant gametes) all over itself and then move on to drink
from another flower, which will receive the pollen of the old, plus dust the insect with its own.
This process is called entimophylly (pollination via insects). Most angiosperms are both male
and female. Many plants like this can pollinate with themselves. Because of adaptations such as
these, Angiosperms generally grow faster and reproduce surer than most conifers, leading to
them taking over most forests in their “old growth” stage, as the final wave of assault by plants
on rocks. They will remain that way until a new phylum of plants evolves. There are two classes
within this phylum, monocot and dicot. Monocot’s seeds have one seed leaf, parallel veins, and
tend towards fibrous roots. The number of floral parts is often a multiple of three. The vascular
bundles are distributed throught the stem. Dicot’s seeds have two seed leaves, branched veins,
and tap roots. Their floral parts are often multiples of four or five and their vascular bundles are
arranged in a ring about the stem. Although it is not a rule, monocots are more closely associated
with grasses while dicots are more often trees
