Question

The simplest mechanical tissue giving mechanical support to living cells in process of elongation is

• A. Sclerenchyma
• B. Parenchyma
• C. Collenchyma
• D. Both A and C

Answer 1

The correct option is C Collenchyma

Collenchyma tissue is composed of elongated cells with irregularly thickened walls. They provide structural support, particularly in growing shoots and leaves. Collenchyma cells are usually living and have only a thick primary cell wall made up of cellulose and pectin. Cell wall thickness is strongly affected by mechanical stress upon the plant.

So, the correct answer is option C.
