Girth of stem increases due to
Girth of stem increases due to
- apical meristem
- lateral meristem
- intercalary meristem
- vertical meristem
Answer
Girth of the stem increases due to lateral meristematic tissues. They are found beneath the bark (called cork cambium) and in 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.
The apical meristem is situated at the growing tip of stems, root and also at the apices of leaf. They bring about elongation, i.e., increase in height (primary growth) of the plant. Intercalary meristem are located at base of leaf and internode and produces an increase in the length of an organ.
The correct option is B.
