Explanation:

- Root tip: The root tip contains the apical meristem, responsible for root elongation and growth.

- Lateral sides of stem: This is where lateral meristems (cambium) are found, which are involved in increasing the girth of the plant through secondary growth.

- Base of leaves: Correct Answer - In grasses, the intercalary meristem is located at the base of the leaves. It allows the leaves to elongate and regrow after being cut or grazed. Grass regrowth after mowing is due to this meristem.

- Shoot tip: The shoot tip consists of the apical meristem, responsible for the elongation of the plant stem and production of new leaves.
