AP BIOLOGY

Detailed explanation-1: -The root apical meristem, or root apex, is a small region at the tip of a root in which all cells are capable of repeated division and from which all primary root tissues are derived. The root apical meristem is protected as it passes through the soil by an outer region of living parenchyma cells called the root cap.

Detailed explanation-2: -The apical meristem is a group of cells that retain the ability to continue divisions, forming new cells continuously as the plant grows. This PRIMARY growth is responsible for growth in height.

Detailed explanation-3: -The Root Apical Meristem (RAM, for short) Just below the tip of the root, there is a region of small, densely packed cells that are actively dividing.

Detailed explanation-4: -Apical meristem: These meristems are present at the tip regions of root, shoot, and leaves. They are the active regions in the cell division which helps in the growth and the elongation of root and shoot. It gives rise to new leaves and hence these are referred as primary tissues in the plant growth.

Detailed explanation-5: -Apical Meristem These are present at the tips of the roots and shoots and helps in the increase of the height of the plants. Various cell divisions facilitate the growth of the cells in the roots and shoots and help in cellular enlargement.
