Question

Which of the meristem is responsible for secondary growth?

• A. Apical
• B. Lateral
• C. Intercalary
• D. Basal

Answer 1

The correct option is B Lateral

Secondary growth refers to the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken.

Secondary growth occurs in most seed plants, but monocots usually lack secondary growth.

Lateral meristem gives rise to secondary phloem and secondary xylem. It consist of the vascular cambium and the cork cambium. Thus, option B is correct.

Apical meristem, basal mristem and intercalary meristem causes primary growth.
