Solution
Simple tissue:
These tissues are composed of structurally and functionally similar cells.
They are of three types.
(i) Parenchyma:
It is widely distributed in plant bodies such as stems, roots, leaves, flowers, and fruits. Its cells are isodiametric and contains live protoplasm. It serves as a food storage and packing tissue. It also stores waste products of plants.
(ii) Collenchyma:
It is located below the epidermis of dicot stem and petiole. It consists of living cells and is characterised by an extra deposition of cellulose at the corners. It is a mechanical tissue in young plants. It also provides elasticity to the plant, particularly stem of dicots.
(iii) Sclerenchyma:
It consist of dead lignified cells. It has two types of cells—that is, fibres and sclereids. It occurs in abundance or in patches in definite layers in stems, roots, veins of leaves, hard covering of seeds, and nuts. It provides mechanical support to the plant.
