Question

Which of the following tissue provides mechanical support to the growing parts of the plants such as young stem and petiole of a leaf ?

• A. Parechyma
• B. Sclerenchyma
• C. Collenchyma
• D. Chlorenchyma

Answer 1

The correct option is C Collenchyma

A. Parenchyma : This tissue forms the major component within the plant organs. The parenchyma performs various functions like the photosynthesis, storage, secretion.

B. Sclerenchyma : This tissue consists of dead cells without protoplast. Sclerenchyma provides the mechanical support to the organs.

C. Collenchyma : This tissue occurs in layers below the epidermis in most of the dicots. They provide the mechanical support to the growing parts of the plant such as young stem and petiole of the leaf.

D. Chlorenchyma : chlorophyll-containing parenchyma of plants. Chlorenchyma cells carry out the photosynthesis and manufacture food.

So, the correct option is C.
