Question

Which one of the following plant tissues causes growth in girth of stem and root?

• A. Apical meristem
• B. Intercalary meristem
• C. Lateral meristem
• D. None of the above

Answer 1

The correct option is C Lateral meristem

Apical meristem is present at the tip of shoot and root. So, it can increase plant length.
Intercalary meristems are present in stems at the base of nodes and leaf blades. Cells of such meristems can divide and form new cells and can increase the length of internodes and in turn, plant's length.
Lateral meristems are vascular cambium and cork cambium. They are responsible for the secondary growth of plants. They increase plant's diameter.
