Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The apical meristem in the root:
A
is located behind the root cap
B
produces cells which become incorporated into the root cap
C
gives rise to the primary meristematic tissues
D
is a region of active cell division
E
all of the above
Explanation: 

Detailed explanation-1: -The meristems which occur at the tips of roots and shoots and produce primary tissues are called apical meristems. Hence apical meristem is present in all root and shoot tips.

Detailed explanation-2: -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-3: -Apical meristem is present at the growing tips of stems and roots. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.

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: -The apical meristem of the root is present in all the roots. Hence, the correct answer is option (D).
