Anatomy of Flowering Plants
271370
A plant tissue when stained showed the presence of hemicellulose and pectin in cells wall of its cells. The tissue is called
1 collenchyma
2 sclerenchyma
3 xylem
4 meristem
Explanation:
(a) Collenchyma is living mechanical tissue, found beneath the epidermis (i.e., hypodermis) of herbaceous dicot stem.
The intercellular spaces in this tissue are absent because in intercellular spaces at the corner of cells thickenings of cellulose and pectin develop due to which the cell wall become rigid and thick at corners.

Various functions like photosynthesis, storage, excretion performed by
1 sclerenchyma
2 collenchyma
3 parenchyma
4 aerenchyma
Explanation:
(b) Parenchyma is the common simple tissue. This is the most primitive tissues from which other tissues are evolved and hence also called as fundamental tissue. The main function of parenchyma is storage of food.
Photosynthesis, respiration, secretion, assimilation, etc. are some of the important processes which occur in parenchymatous cells.

Sclerenchyma are usually protoplasts____and_____
1 live, without
2 dead, with
3 live, with
4 dead, without
Explanation:
(d) Sclerenchyma consists of long, narrow cells with thick and lignified cell walls having a few or numerous pits. They are usually dead and without protoplasts. They are simple dead mechanical tissue occuring in mature organs of plants body. They are chiefly distributed in cortex, pericycle, xylem and phloem region.

The_____occurs in layers below the epidermis in dicotyledonous plants.
1 parenchyma
2 sclerenchyma
3 collenchyma
4 aerenchyma
Explanation:
(c) The collenchyma occurs in layers below the epidermis or outer layer of cells in young stems and in leaf veins in dicotyledonous plants. Collenchyma cells are elongated cells with irregularly thick cell walls that provide support and structure. Their thick cell walls are composed of the compounds cellulose and pectin.
