The phloem is responsible for the conduction or transfer of manufactured food from the area of their synthesis to the other part of the plant. Collenchyma is one of the three fundamental tissues in plants. The main supporting tissues in plants are parenchyma, collenchyma, sclerenchyma (fibre) and wood (xylem). They are composed of cells with thick cell walls that whithstand mechanical forces. 1. Structure: The phloem tissues are made up of four cells. Strengthening: Two major supporting tissues namely sclerenchyma and collenchyma are two distinct forms of strengthening cells found in plants. i. Sieve tubes: These are made of elongated rows of cylindrical cells arranged vertically. Distinct shape: Supporting tissues generally give distinct shapes to different plant species. There epidermal layer is one-cell thick. When the chloroplasts are present in the tissue, they carry on photosynthesis. ii. A mature vascular plant (any plant other than mosses and liverworts), contains several types of differentiated cells. These are fibres and sclereids. Ask your question. Location: Parenchyma tissues are found in the cortex of stem, phloem, root, leaf, mesosphyll, storage tissues and xylem. Both cells provide strength and support. Tissue contains 4 cell types namely vessel elements, tracheids, xylem parenchyma and xylem sclerenchyma. The main supporting tissues in plants are parenchyma, collenchyma, sclerenchyma (fibre) and wood (xylem). They provide strength and support to the plant. It is responsible for the transport and dispersal of water, nutriments and assimilates. Sclerenchyma slereid are heavily lignified cells which are spherical. It is absent in monocots and in roots. 1. The wood or xylem tissue provides support, strength and shape to the plant. ii. Resilience and Flexibility: The supporting tissues also provide the necessary materials which make the plants resilient and flexible thereby preventing the plants from being broken by the bending and twisting movements caused by strong winds. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation. The balance sheet always balances because of the use …, Tabulated work is made more effectively by ruling lines either horizontally or vertically. Rigidity: The supporting tissues like collenchyma, sclenchyma and wood fibres provide the necessary materials to make the plant strong against any external forces. Xylem is a plant tissue specially designed for transporting water and nutrients. Collenchyma is a living tissue of the aerical organs of vascular plants, mainly characterized by thick, pecto cellulosic primary cell walls, typically non-lignified.Collenchyma characteristically occurs in a peripheral position in stems and leaves, particularly in petioles. iii. This video is unavailable. 2. They are present in the leaf mesophyll to partake in the synthesis of food. Xylem tracheid are non- living elongated tapering cell with thickened lignified wall with  pith  that  allow  the passage of  water and dissolve mineral salt. In the vascular bundles, the xylem vessels and fibres which are lignified add mechanical strength to the stems and roots of plant. • Important supporting tissues are turgid parenchyma, collenchyma, sclerenchyma and xylem. Meristematic Tissue: • Cells of meristems divide continuously cells are similar in structure & have thin cellulose cell walls may be spherical, oval, polygonal or rectangular in shape contain few vacuoles • Found in regions of the plant that grow, mainly at tip of root & stem. It aids to strengthen the stem. Their cell walls consist of cellulose, hemicellulose, and lignin. Phloem parenchyma: These are similar to the parenchyma cells earlier discusses. • Support in plant is achieved through cell wall components and structure, turgidity and arrangement of supporting tissues to form strengthening hollow cylinders, solid rods and central solid cylinders.

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. It is large and made of parenchyma and extends between the vascular tissue. Parenchyma cells are the most common ground tissue cells. transport water and minerals. This increase in size of cells which is called secondary thickening is responsible for the increase in size of the trunks of many trees. Sclerenchyma is the supporting tissue in plants. The cells are flexible and thus allow the bending and twisting strains to which the stem, roots and leaves of plants are often subjected. It consist of the xylem, phloem and cambium. Types of Supporting Tissues in Plants. Structure: The cells of collenchyma tissues are living, elongated and unevenly thickened at the corners. Parenchyma tissue: these may be spherical or elongated cells with large vacuoles filled with cell sap. They assist in conduction of food substance. 5. Xylem tissue is one of the major plant tissues that many have heard at least once. Which plant tissues are responsible for giving a plant strength and support? 8. There are two types of sclerenchyma. Sclerenchyma: This layer is found on the outer part of vascular bundles. It gives firmness and rigidity to the stem of herbaceous plant Vascular plants have up to three types of supporting tissue: The collenchyma, a tissue of living cells, the sclerenchyma, a tissue of nearly always dead cells, and. These are sieve tubes, phloem parenchyma, companion cells and phloem fibres. Functions Of Supporting Tissues In Plants. The tissue is located within the vascular bundles of all plants be it in the roots, stems and leaves. All Rights Reserved. Some tissues contain only one type of cell. All rights reserved, 2020. Epidermis : It is usually present in the outermost layer of the plant body such as leaves, flowers, stem and roots. iv.

The cell are living and they conduct mainly manufacture food. Conduction: Some supporting tissues especially xylem and phloem tissues are known to also conduct water and manufacture food respectively within the plant. Sclerenchyma fibres known simply as fibres provide flexibility and strength – two of the special functions of the strengthening tissues in plants. Both of them consist of deal cell in which the cell wall are heavily thickened with deposit of lignin. Fibres: Fibres are similar to sclerenchyma fibres. ii. Plant Tissues. Parenchyma tissues are founds in the cortex of stem, phloem. Cambium is found between the phloem and xylem. Hence when the cells of the parenchyma tissue are fully expanded with water (turgid), they give rigidity and strength (hydrostatic support). Above and beyond tissues, plants also have a higher level of the structure called plant tissue systems. Protective Tissue : It includes epidermis and cork. Secondly, they assist to provide support to the entire plant. The cell are flexible and this allow the bending and twisting strain to which the stem , root and leaves  of plant are often subjected.
