Question

Cells of this tissue are living and show angular wall thickenings. They also provide mechanical support. The tissue is

• A. xylem
• B. sclerenchyma
• C. collenchyma
• D. epidermis

Answer 1

Answer: (C)

collenchyma

A. Xylem: It is the chief conductor of vascular plants responsible for the conduction of water and inorganic solutes.

B. Sclerenchyma: Young cells are living but mature cells become dead due to the deposition of suberin on the cell walls.

C. Collenchyma: Cells of collenchyma are living, and show angular wall thickenings because of deposition of pectin and cellulose. The tissue has the capacity to expand and gives tensile strength to the body.

D. Epidermis: The epidermal cells vary in their shape and size. They are generally compactly arranged, forming a continuous layer without or with very small intercellular spaces.

So, the correct answer is 'Collenchyma'.
