Question

3. Assertion (A): lateral meristems add thickness of plantsReason (R ): lateral meristems divide only in one plane

Answer 1

Answer:

assertion is true and reason is false.

Explanation:

lateral meristem divides side ways and increases girth of plant.

Answer 2

Assertion - True

Reason - True

Along the side of the stem, there are lateral meristems. Only one layer of rectangular cells makes up the lateral meristems, which divides exclusively in single plane and produces new vascular tissues on both sides. Therefore, lateral meristems add thickness of plants. They are also known as secondary meristems as they are responsible for secondary growth in maturing plants. There are two types of lateral meristems - cork cambium and vascular cambium.
