• A. All of the above
• B. Primary meristem - Wound healing
• C. Lateral meristem - Cork cambium
• D. Secondary meristem - Stem girth and thickness

Answer 1

The correct option is A All of the above

Meristems can be classified based on their origin into primary and secondary meristem. Based on their position meristems can be classified into apical, intercalary and lateral meristem.

Primary meristems are responsible for increase in root and shoot length. Eg: Apical meristem. They are also involved in wound healing.

Lateral meristem includes fascicular vascular cambium, interfascicular cambium and cork-cambium or phellogen. Lateral meristems are also known as secondary meristem. They are responsible for increase in stem girth and thickness.
