Question

Apical meristem is found in
A) Roots
B) Stem
C) Both A and B
D) None of these

Answer 1

Hint: Meristematic tissues or meristems are defined as those tissues enclosed within a cell which forever remains young and actively divide throughout their lifetime.

Complete Answer:
Let us first know a little more about apical meristems.
Apical meristem is defined as regions of growth found within the tips of the plant’s shoots and roots as well at the new leaf tip. These meristematic tissues belong to the category of four different tissue types where the remaining three of them collectively represent lateral meristems namely
- Vascular cambium
- Cork cambium
- Intercalary meristem
- Apical meristem
Apical meristem is generally referred to as a dense cluster containing undifferentiated cells.

These undifferentiated cells give rise to various new plant parts.
Option A: Root apical meristem is a small portion present at the tip of the root. The cells present in this region are capable of dividing repeatedly. These cells are the source of all primary root tissues.
Option B: Shoot apical meristem is a region present in the shoot where meristematic cells are found. The cells found are multipotent in nature. It produces primordia which further develops into various organs of the plant which are found above the ground.
Option C: As both A and B are correct. Therefore, this is the correct option.
Option D: As one of the opinions is correct, therefore, this is the incorrect option.

Thus, the correct option is C) Both A and B.

Note: Apical meristem plays a major role in aiding the plants to seek an access to the nutrients and water via its roots and to the light via its leaves.
