Answer 2

Answer:

Meristematic tissue has the ability to divide and to provide growth to plants. Generally, growth of plants occurs from specific region like root and shoot, nodes, girth of stem, leaf base etc.  Types of meristematic tissue are apical meristem, Intercalary meristem, lateral meristem. Apical meristem is present on root and shoot tips of the plant. This tissue divides and results in growth of stem and roots of the plant.

Intercalary meristem is present on leaf base and nodes.

Lateral meristem is responsible for increase in circumference i.e. girth of the stem or root of the plant. Meristematic tissue can divide and redivide upto an extent, after this they lose the ability to divide, thereby, converting into permanent tissue. Growth in plants with meristematic tissue can be easily demonstrated experimentally with help of onion bulbs.
