BIOMOLECULES AND ENZYMES

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. This leads to an increase in the height and girth of plants.

Detailed explanation-2: -The length of the plant is increased by the primary meristems present from the early life of the plant. Apical meristems that are present at the tip of the shoot and sub-terminal region of root mainly helps in the increase in the length of the plant by adding more cells as they show periclinal division.

Detailed explanation-3: -Apical meristem is responsible for increase in length of the plant.

Detailed explanation-4: -The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc. These cells help to increase the length and girth of the plant.

Detailed explanation-5: -Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length. Lateral meristems facilitate growth in thickness or girth in a maturing plant.
