Answer 1

Meristematic tissue, also known as dividing tissue, is present only at specific points where growth occurs. Depending upon its location, it can be divided into three types:

• Apical meristem: It is present at the tips of stems and roots and is responsible for their vertical growth.
• Intercalary meristem: It is present at the base of leaves and internodes and is responsible for the growth of branches and leaves.
• Lateral meristem: It is present in the lateral sides of stems and roots and is responsible for their lateral growth (girth).

Cells of these tissues are very active and because of which they have dense cytoplasm, a prominent nucleus and thin cell wall. These cells usually lack vacuoles. The cells of these tissues are compactly packed together, i.e., they have little or no intercellular spaces.
