Question

The meristem derived from the promeristem is called

• A. lateral meristem
• B. apical meristem
• C. primary meristem
• D. intercalary meristem

Answer 1

The correct option is C primary meristem

Promeristem is the first formed meristem. It is also called the embryonic meristem. This is short-lived and gives rise to the primary meristem.

Primary meristems give rise to the primary permanent tissues of the plant and are responsible for the primary growth of the plant.

Apical meristem and intercalary meristem are types of the primary meristem.
Apical meristems are found in the root and shoot apex and are responsible for the increase in the length of the plant axis.
Intercalary meristems are the leftover cells of the apical meristems and are responsible for the elongation of the internodes. It is responsible for the increase in the length of the plants.
