Assertion (A): Lateral (or cambium) meristem is responsible for the increase in the girth (diameter) of the stem.
Reason (R): Cambium is located near the tips of the root and stem and also on the tips of axillary buds where growth occurs at a faster rate.

- Both A and R are true but R is not the correct explanation of A.

Answer
A is True and R is False.
Reason — A is True as the lateral meristem is responsible for secondary growth, i.e., the increase in girth of stems and roots.
R is False because apical meristem is found at the tips of roots, stems, and axillary buds, and it contributes to length-wise growth.
Therefore, A is True and R is False is the correct option.
