Girth of stem of a plant increases due to division of cells in
Options
- Aapical meristem only
- Blateral meristem only
- Capical and intercalary meristem
- Dboth apical and lateral meristem
Correct answer
B. lateral meristem only
Step-by-step solution
The lateral meristem is a type of meristem that occurs in the lateral areas of a plant. Thus, it is responsible for the secondary growth of the plant, i.e. the increase in girth. Meristematic tissues consist of cells that are actively dividing. They are responsible for the indeterminate growth in plants. They give rise to permanent plant tissues such as vascular tissues, epidermis, phellem, ground tissues, etc.
