Girth of stem increases due to
(a) apical meristem
(b) lateral meristem
(c) intercalary meristem
(d) vertical meristem

Answers (1)

The increase in the girth of a stem is due to the presence of lateral meristematic tissues. They are found in the cork cambium and in the vascular bundles of dicot roots and stems called vascular cambium as thin layers. This increase in the diameter and girth of the plant is called secondary growth.
Apical meristems can be found in the growing parts of a plant like shoot or root tips etc.

The intercalary meristems are located in the internodes at the base of the grass and between leaves.
The correct option is (b) lateral meristem
