Question

Write 8 differences between Sclerenchyma and Parenchyma.​

Answer 1

Parenchyma:

(1) Cells are thin walled and unspecialised. (2) These are living cells. (3) Cells are usually loosely packed with large intercellular space. (4) Stores nutrients and water in stem and roots. (5) Some cells contain chlorophyll, called as chlorenchyma and perform photosynthesis. Other cells have large air cavities, called as aerenchyma, which provide buoyancy to the hydrophytic plants.

Sclerenchyma:

(1) Cells are thick walled and lignified. (2) Tissues are made up of dead cells. (3) No intercellular spaces between the cells are found. (4) Provides strength to the plant parts. (5) The cells are long and narrow, make the plant hard and stiff. The tissue is present in the stem around vascular bundles, in veins of leaves and hard covering of seeds and nuts.

Answer 2

Answer:

Parenchyma Collenchyma Sclerenchyma

These cells are not the specialised cells These cells are specialised cell These cells are specialised

This cell consists of a thin cell wall This cell consists of unequally thin cell wall The cell wall consists of a thick and rigid cell wall
