Question

Bamboo and grasses elongate by the activity of:

• A. Apical meristem
• B. Lateral meristem
• C. Secondary meristem
• D. Intercalary meristem

Answer 1

The correct option is D Intercalary meristem

Intercalary meristems are primary meristems found in monocots such as bamboo and grasses. They are responsible for elongation of the internodes, which in turn is responsible for the vertical growth of plants.

Apical meristem is found in root and shoot apices of both monocots and dicots. They are responsible for primary growth of plants, which include, increase in hieght.

Lateral meristems are secondary meristems which help in secondary growth or increase in width or girth of the plant parts.
