tabulate the difference between parenchyma ,collenchyma and sclerenchuma on the basis of location structure and function
Answers
Answer:
Parenchyma cells are found in every soft part of the plant, but collenchyma cells are found in specific part of the plant like leaves, stems, and petioles, whereas sclerenchyma cells are found in mature parts of the plants or trees. ... Parenchyma has a thin cell wall of their cells, and are made up of cellulose.
ANSWER:-
1.)Parenchyma:-
1.)Parenchyma is found in cortex and pith pf stems and roots in the mesophyll of leaves.
2.)They have thin cell wall.
3.)Cells are loosely packed.
4.)There is large intercellular spaces between the cells.
5.)It stores food,water and nutrients.
6.)It also provides support to the plants.
7.)Cells are living.
2.)Collenchyma:-
1.)Collenchyma is found in leaf stalks and below the epidermis and leaf midribs
2.)Cells are irregularly thickened at the corners due to the deposition of pectin.
3.)Cells are not loosely packed.
4.)There is very little intercellular spaces.
5.)It provides mechanical support to the plant and also provides elasticity to the plants.
6.)It allows easy bending of the plants without breaking.
7.)Cells of this tissue are living.
3.)Sclerenchyma:-
1.)Sclerenchyma is found in stems,around vascular bundle,veins of the leaves and in the hard covering of nuts and seeds.
2.)Cells are very thickened due to the presence of lignin which hardens them.
3.)Cells are not loosely packed.
4.)Due to the thick walls.there is no intercellular spaces.
5.)It makes plant hard and stiff.
6.)It gives rigidity,flexibility and elasticity.
7.) Cells of this tissue are dead.
