Detailed explanation-1: -Meristematic tissues are responsible for plant growth. They are present at the tips of roots, stem and branches. The cells present in these tissues constantly divide to produce new cells.

Detailed explanation-2: -A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells constantly divide to give rise to various organs of the plant and keep the plant growing.

Detailed explanation-3: -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).

Detailed explanation-4: -Intercalary Meristem It is located in the leaves and internodes at the intercalary position. These help to increase the length of the internode. It is found in grass, monocots and pines. It is a part of apical meristem and adds to the height of the plant.
