Question

Which meristem helps in increasing girth?
(a) Lateral meristem
(b) Intercalary meristem
(c) Primary meristem
(d) Apical meristem

Answer 1

Answer:

(a) Lateral meristem

Explanation:

Answer 2

The meristem that helps in increasing the girth is (a) Lateral meristem.

• The vascular cambium, the cork cambium and the inter-calary meristems are the lateral meristems.
• Lateral meristems are arranged tandem with the organs in which they occur. They increasing the thickness of the plant body by secondarily rising.
• Secondary plant growth occurs because of the cell division of lateral meristems that help to increase the plant thickness.
• The secondary growth occurs in vascular plants because of the development of the two lateral meristems-the cork cambium and the vascular transition.
