Answer 1

Answer:

please mark as brainlist and folow me

The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem allows plant stems and roots to grow longer (primary growth) and wider (secondary growth).

Answer 2

Answer

Correct option is

Both A and B

Intercalary meristems are present in stems at the base of nodes and leaf blades. Cells of such meristems can divide and form new cells.

Lateral meristems are vascular cambium and cork cambium. They are responsible for the secondary growth of the plant. They increase plant diameter.

Apical meristem is present at the tip of root and shoot. Cells of apical meristem divide and give rise to new cells. This process increases the length of root and shoot.
