In plants, apical meristem are typically found at: The tip of the shoot; Root of the plant; 5. The collenchyma is the typical supporting tissue of the primary plant body and growing plant parts. Plant Tissue – Meristematic Tissue, Permanent Tissue – Simple Permanent Tissue: Parenchyma, Chlorenchyma. Dermal tissue: Consisting primarily of epidermal cells, dermal tissue covers the entire surface of a plant. Sclerenchyma is the supporting tissue in plants. The Sclerenchymatous tissue, which is a type of permanent tissue makes up the husk of the coconut. e.g., the husk of coconut is made up of sclerenchymatous tissues. Cells of cork are dead and compactly arranged without intercellular spaces. Plant tissue system is also grouped into various tissues based on their functions. They take up a specific role and lose the ability to divide. Bark, in woody plants, tissues external to the vascular cambium (the growth layer of the vascular cylinder); the term bark is also employed more popularly to refer to all tissues outside the wood.The inner soft bark, or bast, is produced by the vascular cambium; it consists of secondary phloem tissue whose innermost layer conveys food from the leaves to the rest of the plant. In some plants like desert plants, epidermis has a thick waxy coating of, As plants grow older, the outer protective tissue undergoes certain changes. Collenchyma walls are interspersed with … Most of the plant tissues are dead, since dead cells can provide mechanical strength as easily as live ones, and need less maintenance.
