1. The document outlines the main parts and functions of plants. It discusses how plants are made up of root and shoot systems, with each part playing specialized roles. The root system anchors the plant underground and absorbs water and nutrients, while the shoot system grows above ground and carries out processes like photosynthesis, reproduction, and transporting water and nutrients.
2. Key parts of the shoot system are then described in more detail. The stem provides structure and transports fluids within the plant. Leaves perform photosynthesis and gas exchange. Flowers contain the reproductive organs and produce seeds. Fruits develop from flowers to protect and disperse mature seeds.

Which is a common trait among all land plants?
Vascular tissues transport water and nutrients, and provide support
Seeds facilitate survival and dispersal of the species
Flowers facilitate cross-pollination
The embryo is protected within maternal tissues
The haploid phase of the life cycle is the dominant phase
Flowers facilitate cross-pollination
The embryo is protected within maternal tissues
The haploid phase of the life cycle is the dominant phase
Solution
First we see common traits of land plants and then see listed traits in details one by one:
1. Ability to withstand desiccation. Extant land plants have a cuticle and guard cells.
2. Ability to withstand the effects of more intense radiation, particularly DNA-damaging
radiation. Extant land plants have several compounds in their vacuoles that absorb UV. Since the
vacuole of a plant occupies most of a mature cell, this helps protect the DNA in other organelles.
3. Ability to protect their spores from desiccation. Early land plants have spores that are encased
in a sporopollenin wall. Sporopollenin is a very resistant polymer, resistant to UV and almost
everything including desiccation, squashing, etc. To remove sporopollenin from spores, one boils
them in a mixture of acetic and hydrochloric acid.
4. Ability to move solutions from the ground to portions of the plant that are not in contact with
the ground, and from the photosynthetic portions of the plant to non-photosynthetic portions.
Some land plants do this better than others.
5. Ability to support themselves. Aquatic plants float; terrestrial plants cannot do so. Most
terrestrial plants have lignin in some of their conducting cells. There is some debate as to
whether this was selected for by the advantages of growing tall or the need to protect against
embolism in the conducting cells. Since both are important, it seems most realistic to accept that
both contributed to the success of plants with the ability to manufacture lignin, the tracheophytes
or vascular plants.
6. Ability to acquire the carbon dioxide required for photosynthesis from the atmosphere. This
ability is associated with stomatal cells, specialized cells that surround openings (stomates) in the
outer cell layer of land plants.
Now we see Options given one by one:
Vascular tissues transport water and nutrients, and provide support
Transport of Water and Minerals:
The xylem tissue transports water and minerals. It consists of interconnected vessels and
tracheids organized into continuous conducting tubes stretching from the roots to the leaves.
These tubes carry water and minerals to all parts of the plant.
Plants absorb water from the soil through the root and transport it to the stem, leaves and
flowers. Roots have root hairs that are unicellular, thin-walled outgrowths of the epiblema (skin
of the root).
The root hairs are in close contact with the thin film of water surrounding the soil particles.
There are mineral salts such as nitrates, chlorides, sulphates, phos.

Background Angiosperms (flowering plants) are the largest Phylum in .pdfrushabhshah600
Background Angiosperms (flowering plants) are the largest Phylum in the plant kingdom
Plantae, (Note that the Phylum A may also called Anthophyta or Magnoliophyta in different
classification systems.) These plants have true roots, stems, leaves, and flowers. The roots grow
into the soil to anchor the plant in place and take up water and nutrients. The leaves are above
ground and act as the main organs for photosynthesis. Stems provide above ground support for
the plant and operate as conduits to move nutrients and water throughout the plant. Flowers
contain the male and female reproductive organs of the plant. Assignment Details Part 1 Plants
develop specialized roots, stems, leaves, and flowers to make them better adapted to their
environment. People exploit many modifications as vegetables. An example of this is the taproot
of carrots. The carrot plant stores sugars in the taproot to supply energy for the formation of
flowers in later development. People dig up and eat the taproots while the sugar content is still
high. Complete the following: Describe the anatomy (structure) and physiology (function) of a
plant. Is the structure of your plant a modification from the standard root, stem, leaf, or flower?
Explain how this structure differs from the standard root, stem, leaf, or flower. Compare the
plant that you have chosen, its structure, and its function with 1 or more of your classmates\'
choices. Part 2 Animals are important for humans in ways other than providing food.
Medicines, clothing, beauty, fuel, air quality, building materials, and industrial products are a
few of the ways in which humans exploit animals. Complete the following: Choose l product or
benefit that people get from animals (besides food), describe it, and explain how people benefit.
Which do you think is the most important benefit of animals? Select 1 benefit and explain. List
3 adaptations that animals have that plants do not have. Provide references in APA format. This
includes a reference list and in-text citations for references used throughout the assignment
Solution
1. the normal function of roots is fixation of the plant in the soil absorption of water and
Minerals from the soil and conduction of the materials to the stem but in some plants roots
perform special functions like storage of food materials(carrot,raddish) respiration(rhizopora)
vegetative reproduction (sweet potato)support(betel vine) photosynthesis(orchids).
Betel vine:
Weak Climbing Plants produce some advantitious roots which cling to the supports and help the
plants in climbing they sometimes they secrete sticky substance or a disc like structures for this
purpose.
Betel Vine is a plant having climbing roots these adventitious roots are produced from their
nodes which help them to climb over a support another example is money plant.
These roots are aerial roots which twist and clasp the support to help plant to vlimb.
Normal rootsd show positive geotropism but these climbing roots show negativ.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

1. 1. A plant is a living organism. It is made up of different parts, each of which has specialized
function. Not all parts of plant need function properly. If one part is not functioning properly
the whole plant will suffer. The basic parts of a plant is the Root System and Shoot System.
The Root System usually underground. It anchor the plant in the soil, absorb water and
nutrients, conduct water and nutrients, and food storage. Whereas the Shoot System usually
above the ground. Consist of the stem, the leaves, flower, and fruit. The function of shoot
system are elevates the plant above the soil, photosynthesis, reproduction and dispersal,
and then food and water conduction. 1. Root The root system is underground part of the
plant. The function of the root include : a. Holds a plant erect and in one place. b. Holds a
plant firmly to the soil. c. Absorb water and minerals from the soil and pass them to the plant.
d. Store food for some plant.
2. 3. 2. Stem The plant stem is a component of the shoot system. The function of stem include :
a) Stem Support. It supports the leaves, flowers and fruits and connects them with the roots.
b) Stem Conduct. It conducts water, nutrients and the products of photosynthesis to and from
roots and leaves. It accommodates the transport system which is necessary for the vertical
and lateral movement of water and sap within the plant body. c) Stem Store. It helps store
water as in cacti, and store the products of photosynthesis, as in the trunk of sago palm
(Metroxylon sagu) and sweet palm (Arenga pinnata) which store large stock of starch; d)
Stem produce new living tissue. The plant stem serves as a means of asexual reproduction
in many plant species. 3. Leaves The plant leaves are the part of the shoot system which
serves as the chief food producing organ in most vascular plants. The function of leaves are :
a. Photosyntesis. This is the process of producing food of the plant. This process essentially
involves the absorption of light mainly by the chlorophyll pigments, to turn water (H2O) and
carbon dioxide gas (CO2) into sugar and oxygen gas (O2). b. Transpiration. It is process of
the loss of water through the leaves via stomata and cuticle. c. Gas Exchange. These
process take place in stomata. This is open and close to regulate the passage of gases to
and from the leaves.
3. 4. 4. Flower Flower is component of the shoot system. The flower contains the reproductive
organs, and has function to produce seeds. The stamens produce the male sex cells, which
are carried in the pollen grains. The carpel produces the female sex cells, or ovules. After
fertilization, portions of the flower develop into a fruit containing the seeds. 5. Fruits The fruit
is in fact described as a reproductive organ of plants just like the flower and seed. The fruit is
mature, ripened ovary that contains the seeds and protects them while they are developing.
The main function of the fruits are : a. Fruits protect the seeds. The fruit serves as a physical
barrier between the seed and the external environment during seed development. The
developing fruits (ovary) promote ovule or seed development by preventing dessication and
ensuring moist environment for the embryo. In addition, the pericarp or fruit wall hinders easy
access to seeds by some insects and other herbivores. Some fruits also contain toxic
substances or the outer exocarp is supplied with thorny projections which serve as anti
herbivory defenses. b. Fruits aid in the dispersal of mature seeds. Wind, water, animals, and
explosions help disperse some seeds. Seed dispersal importance of colonization, survival of
species, wildlife preservation, community structure (assemblages of plants and animals),
global climate, and environmental quality.
