Question

Differentiate between Parenchyma, Collenchyma and Sclerenchyma on the basis of structure.

Answer 1

Explanation:

Parenchyma

Consist of live unspecialized cells having thin cell wall.They are loosely packed and have large intercellular space (space between the cells).Provides support to the plant and present in all parts like roots, stems, leaves, fruits and seeds.

Consist of live unspecialized cells having thin cell wall.They are loosely packed and have large intercellular space (space between the cells).Provides support to the plant and present in all parts like roots, stems, leaves, fruits and seeds.Storage of food (eg. Fruits) and water (in stems eg. cactus) is the main function.

Collenchyma

The cells of the tissue are living, elongated, and have irregularly thickened corners.The term was coined by Schleiden.It provides flexibility and mechanical support to the plants.

Sclerenchyma

The tissues are dead which makes the plant hard and stiff (eg. Husk of coconut).

The tissues are dead which makes the plant hard and stiff (eg. Husk of coconut).Structurally they are long and narrow.
