AP BIOLOGY

Detailed explanation-1: -The very tip of the root is covered by a thimble-shaped root cap, which serves to protect the growing tip as it makes its way through the soil. Just behind the root cap lies the apical meristem, a tissue of actively dividing cells.

Detailed explanation-2: -The apical meristem is the growth region in plants found within the root tips and the tips of the new shoots and leaves. Apical meristem is one of three types of meristem, or tissue which can differentiate into different cell types. Meristem is the tissue in which growth occurs in plants.

Detailed explanation-3: -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.

Detailed explanation-4: -Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root. The girth (width) of the stem or root increases due to lateral meristem. Intercalary meristem is present at the base of the leaves and internodes (between two nodes) on twigs.
