It has many xylem bundle radially arranged, It gives firmness and rigidity to the stem of herbaceous plant, The xylem tissue provide support and shape to the plant. Phloem: Phloem is responsible for the conduction of manufactured food from their area of synthesis, e.g. Plant Tissues. Secondary growth 1. The phloem sieve tubes– are made up of elongated row of cylindrical cell which are arranged   vertically. (Solved) State two adaptations of Guard cell to its function in plant tissue. Tags: Question 6 . Cambium: Cambium is found between the phloem and xylem. They assist in the conduction of food substances. The cells of the fiber are narrow polygonal, elongated with tapering end. Log in. The cortex is made up of three tissue which are( collenchyma) on the outside, a middle( parenchyma) and inner( endoderm). Parenchyma tissue: these may be spherical or elongated cells with large vacuoles filled with cell sap. When the vacuoles are filled with sap, parenchyma tissues gives firmness and turgidity to the stems of the herbaceous plants. Above and beyond tissues, plants also have a higher level of the structure called plant tissue systems. This increase in size of cells which is called secondary thickening is responsible for the increase in size of the trunks of many trees. Both of them consist of deal cell in which the cell wall are heavily thickened with deposit of lignin. Vessels: Vessels are long tabular structures that are formed by the fusion of several elongated cells stacked one on top of another. Plants like Hibiscus, jute and sisal are known to contain some of the strongest plant fibres hence they are used for making cloth, sacks, mats and ropes. They prevent the inner cells from injury, infection and loss of water. 5. Find an answer to your question What are Supporting tissue in plants?

Plants generally are known to possess supporting tissues which give them definit shape, strength, rigidity and resistance against external forces such as wind and water to which they are continously subjected. ii. They are composed of cells with large vacuoles. It is large and made of parenchyma and extends between the vascular tissue. Its supporting value is increased by its peripheral position in the parts of stems, petioles and leaf mid-ribs. Collenchyma cells thicken their cell walls with extra cellulose to help support the plant. Root, leaf mesophyll, storage tissue and xylem. Supporting tissues in plants? Ask your question. Parenchyma tissues are founds in the cortex of stem, phloem. answer choices . Answered Write short note on supporting tissue in plants 2 1. Hence when the cells of the parenchyma tissue are fully expanded with water (turgid), they give rigidity and strength (hydrostatic support). (i) Centriole. The cell also help in food storage. Log in. The function of the cambium which contributes to the growth of tree trunks in width or girth (secondary growth or thickening) provides the necessary support and strength to plants. The parenchyma cells of the pith when fully turgid, push outside and this force is restrained by the inelastic epidermis. 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. 2 (i) Centriole. Protective Tissue : It includes epidermis and cork. There are over \(\text{200 000}\) types of plant species in the world. Log in. The complex tissues of the plant aid in this overall effort to supply the roots with food as they supply the leaves with water and nutrients. Permanent tissue is made up of simple and complex tissues. Cortex: The cortex is found between the epidermis and vascular bundles of a dicotyledonous stem. ii. Sclereids unlike fibres are not too elongated but have great strength like fibres. The supportive tissues of plants are collenchyma and sclerenchyma. Structure: The wood or xylem tissue is made up of many cells. It is also a conducting tissue as it helps to conduct water and dissolved mineral salts from the roots to the leaves. The cell are flexible and this allow the bending and twisting strain to which the stem , root and leaves  of plant are often subjected. answer choices . The balance sheet always balances because of the use …, Tabulated work is made more effectively by ruling lines either horizontally or vertically. It is absent in monocots and in roots.

Sclerenchyma slereid are heavily lignified cells which are spherical. The wood or xylem tissue provides support, strength and shape to the plant. Structure: They are composed of cells with large vacuoles and relatively thin wall. The two main forms of plant tissue used in this process are xylem and phloem. State two adaptations of Guard cell to its function in plant tissue. Xylem tissue is one of the major plant tissues that many have heard at least once. These are tracheids, vessels, fibres and xylems parenchyma. The cambium cells are constantly dividing cells. The xylem is responsible for conduction of water and dissolved minerals salt from soil to the leaf through the root and stem. Rigidity: The supporting tissues like collenchyma, sclenchyma and wood fibres provide the necessary materials to make the plant strong against any external forces. All rights reserved, 2020. Phloem parenchyma: These are similar to the parenchyma cells earlier discusses. 1. 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. Location: Parenchyma tissues are found in the cortex of stem, phloem, root, leaf, mesosphyll, storage tissues and xylem. The scelerenchyma (fibres) give flexibility to plants and prevent them from breaking up easily. 4. • 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. i. Collenchyma cells provides strength and supports in young growing plant parts such as stems, petioles and leaf blades. They are present in all part of the plant e.g cortex, pith, phloem, fruit and seed coat. Xylem parenchyma– are similar to parenchyma tissue. 3. Collenchyma is made of elongated, living cells that accumulate cellulose and pectin in some regions of the cell wall,giving them an unequal thickness and thus providing flexibility. The cells also help in food storage. Note: The vascular tissues (xylem and phloem) are found mainly in the roots, stems and leaves of plants. The entire plant body be it internal or external parts provide the necessary support to plants. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
