Vascular plants evolved adaptations for survival on land such as obtaining and preserving water. Seed-bearing plants were most successful with adaptations like producing seeds that could be dispersed independently of water. Gymnosperms were the first seed-bearing plants but had exposed seeds, while flowering plants (angiosperms) produced specialized reproductive structures called flowers and fruits to enclose and nurture seeds. Angiosperms diversified greatly and many provided benefits to humans like domesticated grains.

Parts of a Flower
Sepals
Petals
Receptacle
Pistil
Stamen
Stamen
The stamen (plural stamina or stamens) is the pollen-producing reproductive organ of a flower.
Filament- Supports the Anther
Anther- Produces Pollen Grains
Pistil
The ovule producing part of a flower.
The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates.
Peduncle
The stalk of a flower.
Types of Flowers
Complete Flowers- have both male and female parts
Incomplete Flowers- have either male or female parts but not both.
Pollination
is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

How Are Flowers Useful to Us?
Flowers are not just beautiful to look at,
but they also serve a vital role in our ecosystem.
Flowers help our ecosystem flourish and attract a plethora of life to the area and facilitate the expansion of our environment. If flowers are cut down or destroyed before pollination can occur, that particular species has a high chance of dying off in that area. In addition, local wildlife will also vanish in that area since they would have no food. Flowers help keep the ecosystem growing and provide new plant life, as well as help sustain local insects and birds.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Introduction: Pioneers In a New World
• Transition from water -> land
began in the precambrian
period with cyanobacteria
(green algae)
• Developed into world’s 1st
plants
• Adaptations necessary for
survival on land
- Obtaining and
preserving water
- Reproduction
3. 23.1: Trends In Plant Evolution
• Vascular plants: most diverse plants w/ internal tissue systems that conduct water
and solutes through roots, stems and leaves
• Seedless vascular plants: whisk ferns, lycophytes, horsetails, ferns
• Gymnosperms: seed-bearing vascular plants
– Cycads, ginkgos, gnetophytes, conifers
• Angiosperms: vascular plants w/ flowers and seeds
– Magnoliids, eudicots, monocots
• Bryophytes: nonvascular plants
– Liverworts, hornworts, mosses
• Root systems: underground absorptive structures of a cumulatively large surface
area
– Rapidly take up soil water and mineral ions
– Anchor for plants
• Shoot systems: stems and leaves absorb energy from sun, CO2 from the air
– Developed taller/branched stems after developing the capacity to
synthesize/deposit lignin in cell walls
• Xylem: vascular tissue that distributes water and dissolved ions in plants
• Phloem: vascular tissue that distributes dissolved sugars and other photosynthetic
products
4. 23.1: Trends In Plant Evolution
• Cuticle: protective waxy coat that helps conserve water on hot, dry days
• Stomata (stoma): tiny openings across surfaces of leaves and some stems to
control CO2 absorption and restrict evaporative water loss
• Gametophytes: gamete-producing bodies that dominate the haploid phase of algal
life cycles
– mostly aquatic plants
• Sporophyte: multicelled diploid plant body
• After a diploid zygote undergoes mitosis->Forms spores: haploid resting cells
– fertilization could be timed with suitable environmental conditions
– Diploid dominance is an adaptation to land
• Heterospory: plants that produce 2 types of spores (both seedless an seed-
bearing)
• Homospory: plants that produce one type of spore
• Pollen grains: cellular structures that become mature, sperm-bearing male
gametophytes
– Microspores that reach eggs via air currents, insects, and birds
– Contributed to radiation of seed-bearing plants to high/dry habitats
• Seed: an embryo sporophyte, nutritious tissues, and outer coat; Developed from
female gametophytes
5. 23.2: The Bryophytes
• Species of mosses, liverworts, hornworts
– Adapted to moist habitats
– Mosses, however, can be found in deserts as well
• Sensitive to air pollution
• Most common
• Nonvascular: leaf/stem/root parts lack a xylem or phloem
– Instead, have rhizoids: elongated cells/threadlike absorptive structures that attach the gametophytes
to the soil, and absorb water and minerals
• Show three features that were adaptive during the transition to land
– 1. Cuticle: stomata to prevent water loss
– 2. Cellular jacket around parts that produce sperm/eggs: holds in moisture
– 3. Embryo sporophyte: sporophytes that begin life inside a female gametophyte
• Sporophytes remain attached to the gamete-producing body for nutrition (do not disperse)
• Mosses (most common)
– Gametophytes grow in clusters to form cushiony mounds, or grow in branched patterns on tree
trunks (humid conditions)
– Eggs and sperm develop in gametangia at shoot tips of familiar moss plants
– After fertilization, the zygote develops into a mature sporophyte
• Develop a sporangium: stalk and jacketed structure where spores develop
• o Examples
• Peat mosses: used to soak up water (5x more than cotton), used as antiseptic, and also burned
for electricity
• peat bogs: moist mats of the remains of peat mosses
6.
7. 23.3: Existing Seedless Vascular Plants
• Whisk ferns, lycophytes, horsetails, and ferns
• Different from bryophytes b/c sporophytes that develop independently of gametophytes
– sporophytes that have well-developed vascular tissues
– larger, longer-lived sporophyte phase of its life cycle
• Sporophytes can live on land, while gametophytes cannot
• Lycophytes: small club mosses on the forest floor
– “ground pines”
– sporophytes with true roots, stems, small leaves with vascular tissue
– strobili (strobilius) bear spores that germinate, forming small, free-living gametophytes
• heterosporous
• Whisk ferns: not true ferns; resemble whisk brooms
– have rhizomes: short, branched, mainly horizontal absorptive stems that grow underground
– no leaves, made of scale-like branches
– popular ornamental plants common to tropical/subtropical areas
• Horsetails
– sporophytes have rhizosomes
– scalelike leaves whorl around a hollow, photosynthetic stem
– spores produced inside cone-shaped clusters of leaves at shoot tip
– found in streambank muds and other disrupted habitats
• Ferns
– have rhizosomes and fronds: aerial leaves that coil into what resembles a fiddlehead
– sporangia: clusters of spores on the lower surface of the fronds
8. 23.4: Ancient Carbon Treasures
• Lycophyte trees: giant club mosses that developed during the
Carboniferous era
– strobili that produced 8 billion microspores or hundreds of
megaspores
– 40m tall
• 20m tall horsetails
• Many swamp forests had sediments that compressed undecayed remains
of plants into peat mosses
– Pressure transformed the peat into coal: a renewable fossil fuel
9. 23.5: The Rise Of Seed-Bearing Plants
• Most successful vascular plants because
independent of water for fertilization
– Seed ferns, gymnosperms, angiosperms
• Different than seedless vascular plants because:
– Microspores: develop into pollen grains to carry
sperm to female structures (pollination)
– Megaspores: develop within ovules: female
reproductive structures that, when mature, produce
seed
• § female gametophyte, nutrient rich tissue, jacket of
cell layers (to develop a seed coat)
– Traits to conserve water: Thicker cuticles, stomata
underneath leaves
• Pre-Carboniferous: dominated by seed ferns (simlar
to progymnosperms): earliest seed-producing
plants
10. 23.6: Gymnosperms-Plants With “Naked” Seeds
• Gymnosperm sporophyte stages are conspicuous trees and shrubs; the seeds are rather
unprotected ("naked seeds") perched at the surface of reproductive parts.
• Conifers (Coniferophyta)
– The conifers (cone-bearers) are woody trees with needlelike or scalelike
leaves.
– Most are evergreens, some are deciduous.
– Produce true cones: repro. structures in clusters of papery/wood-like
scales that bear exposed to ovules on upper surface
• Lesser Known Gymnosperms
– Cycads (Cycadophyta)
• These palmlike trees flourished during the Mesozoic era, but only about 100
species still exist--confined to the tropics and subtropics.
• They bear massive cone-shaped strobili that produce either pollen (transferred by
air currents or insects) or ovules.
– Ginkgos (Ginkgophyta)
• From the diversity of this group during the Mesozoic, only one species has survived.
• They are remarkably hardy, showing resistance to insects, disease, and air
pollutants.
– Gnetophytes (Gnetophyta) are the most unusual gymnosperms; they live in tropical and
desert areas.
11. 23.7: A Closer Look At The Conifers
• Pine Life Cycle
– The pine tree produces two kinds of cones:
• Male cones produce sporangia which yield microspores
that develop into pollen grains (male gametophyte).
• Female cones produce ovules that yield megaspores
(female gametophyte).
– Pollination is the arrival of a pollen grain on the
female reproductive parts, after which a pollen tube
grows toward the egg.
– Fertilization, which is delayed for up to a year,
results in a zygote that develops into an embryo
within the conifer seed.
• Deforestation and the Conifers
– Although conifers still dominate in certain climates,
their slow reproductive pace puts them at a
disadvantage compared to angiosperms.
– However, deforestation by clear-cutting for their
commercial value has put them at even greater risk.
12.
13. 23.8: Angiosperms - Flowering,
Seed-Bearing Plants
• Characteristics of Flowering Plants
– Only angiosperms produce specialized reproductive structures called flowers.
• Of all the divisions of plants, angiosperms ("vessel seed") are the most
successful and most diverse.
• Most flowering plants coevolved with pollinators--insects, bats, birds, etc.
– There are three major groups of flowering plants:
• Magnoliids include magnolias, avocados, nutmeg, and black pepper
plants.
• Eudicots include familiar shrubs, trees (except conifers), and herbaceous
plants.
• Monocots include grasses, lilies, and the major food-crop grains.
• Representative Life Cycle--A Monocot
– The diploid sporophyte has extensive root and shoot systems; it also retains
and nourishes the gametophyte.
– Embryos are nourished by the endosperm within the seeds, which are
packaged inside fruits.
14. 23.9: Seed Plants And People
• Artificial selection of plants led to the
development of domesticated grains including
wheat and barley (11,000 yrs ago)
• Different trees have been used for their wood
pliability (paper, furniture, rope)
