Question

Wound healing in plants is initiated by

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

Answer 1

The correct option is B Secondary meristem

A secondary meristem is a form of meristematic tissue in plants that is responsible for secondary growth, such as girth or thickness expansion. It is in opposition to the primary meristem, which is engaged in primary growth, such as height or length growth. As a result, unlike the primary meristem, a secondary meristem promotes lateral development rather than vertical growth. It is further distinguished from the primary meristem by the fact that it is formed from permanent tissue. The meristem that develops secondarily from the permanent tissue is known as a secondary meristem. The activity of secondary meristems aids in wound healing in plants.
