Question

The length of a plant axis increases by

• A. Apical meristem
• B. Lateral meristem
• C. Dermatogen
• D. Pleurome

Answer 1

The correct option is A Apical meristem

Meristems which occur at the apices of the stem, root and other branches are called as apical meristems, which bring about the primary growth of the plants, hence, also called as primary meristems. Apical meristem is responsible for the increase in the length of the plant.
Thus, the correct answer is option A.
