Question

Which meristem aids in the growth of the plant's girth?

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

Answer 1

Answer:

A. Lateral meristem

• Secondary growth in plants is caused by cell division in the lateral meristems or secondary meristems, which increases the thickness or girth of the plant.

• The cork cambium and the vascular cambium are the two lateral meristems that create secondary growth in vascular plants.

• In woody plants, secondary development produces wood and thickens the trunk.
