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: -Root apical meristem serves as the source of new cells for root growth. In the root apical meristem, the stem cell niche sustains pluripotent stems cells to ensure a constant supply of cells for continuous root growth.

Detailed explanation-4: -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.

Detailed explanation-5: -Answer and Explanation: Geotropism is the growth of plant roots downward and is the effect that gravity has on a plant organism during its growth.
