Detailed explanation-1: -apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.

Detailed explanation-2: -The lengthening of the stem by apical meristem division is called primary growth. The three types of primary tissues are: protoderm. ground meristem. procambium.

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

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

Detailed explanation-5: -Apical is a description of growth occurring at the tips of the plant, both top and bottom. Intercalary meristem is found between branches, while lateral meristem grow in girth, such as in woody plants.
