Plant Tissues. Copyright © 2020 TIPSINFLUENCER. No. Secondly, they assist to provide support to the entire plant. The general function of the phloem is to conduct manufactured food from their area of synthesis to areas where they are needed. i. Collenchyma cells provides strength and supports in young growing plant parts such as stems, petioles and leaf blades. It prevents the inner cell from injury, infection and water less. It occurs chiefly in hypodermis of stems and leaves. This increases the size of cell which is called secondary thickening which is responsible for the increase in size of the trunks of many trees. Leaves to the areas where they are required. This increase in size of cells which is called secondary thickening is responsible for the increase in size of the trunks of many trees. All the tissues of a plant which perform the same general function, regardless of position or continuity in the body, constitute the tissue system. The wood or xylem tissue provides support, strength and shape to the plant. Xylem vessel :- are long tubular structure that are formed by the fusion of several  elongated cells which are joined. There are two types of sclerenchyma. Join now. They are narrow, elongated cells with very thick walls and tapering end walls. Answers (1) State the functions of the following organelles. Find answers now! 7. The epidermal layer is one cell thick with a protective cell. iii. The cortex is made up of three tissues which are collenchyma (on the outside), a middle parenchyma and inner endodermis. Xylem tissue is one of the major plant tissues that many have heard at least once. ii. 2. 8. Companion cells: They are small and short cells which are vertically elongated like the sieve tube. They are composed of cells with thick cell walls that whithstand mechanical forces. They are present in all part of the plant e.g cortex, pith, phloem, fruit and seed coat. Strengthening: Two major supporting tissues namely sclerenchyma and collenchyma are two distinct forms of strengthening cells found in plants. Parenchyma tissues are founds in the cortex of stem, phloem. Parenchyma tissues are founds in the cortex of stem, phloem. 2 Epidermis : It is usually present in the outermost layer of the plant body such as leaves, flowers, stem and roots. Collenchyma is one of the three fundamental tissues in plants. A herbaceous stem is kept erect by a combination of turgor of its living cells, inelastic cuticle and supporting tissues. They are living cells with cellulose and many air spaces within them. Tissue contains 4 cell types namely vessel elements, tracheids, xylem parenchyma and xylem sclerenchyma. Structure: They are composed of cells with large vacuoles and relatively thin wall. The cells are living and they conduct mainly food. Protection: Some supporting tissues are known to protect the delicate parts of the plants body, e.g. Vascular bundles: Vascular bundles are found in the inner part of the stem. Date posted: February 6, 2018. i. Tracheids: Tracheids are non-living, elongated, tapering cells with thickened, lignified walls which have piths that aid the passage of water and dissolved mineral salts. Location: Sclerenchyma cells are found mainly in the pericycle in the vascular tissues and cortices of roots and stems. They are composed of cell with large vacuoles, The phloem tissue are located within the vascular bundle of all plant, be it in the root, stem and leaf , they are made up of four type of  cells namely. This tissue gives tensile strength to the plant and the cells are compactly arranged and have very little inter-cellular spaces. These help to provide strength and flexibility to plants. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation. xylem tissue. 5. The cells are flexible and thus allow the bending and twisting strains to which the stem, roots and leaves of plants are often subjected. Answered Write short note on supporting tissue in plants 2 Cambium: Cambium is found between the phloem and xylem.

The knowledge of the internal structure of the leaves, stem and roots will assist in the understanding of the mechanism of support in plant. Ask your question. 3. Rigidity: The supporting tissues like collenchyma, sclenchyma and wood fibres provide the necessary materials to make the plant strong against any external forces. Sclerenchyma is found in the covering of seeds and nuts, around the vascular tissues in stems and the veins of leaves. (Solved) State the functions of the following organelles. Functions Of Supporting Tissues In Plants. Sclerenchyma Tissue   is composed of two type of cell namely sclerenchyma fiber and sclerenchyma sclereid. Root, leaf mesophyll, storage tissue and xylem. It is also a conducting tissue as it helps to conduct water and dissolved mineral salts from the roots to the leaves. Structure: The phloem tissues are made up of four cells.
