Examine the figure given below and select the correct option that represents the correct labelling A,B,C and D

	A	B	C	D
(1)	Leaf primoridum	Meristematic zone	Axillary bud	Intercalary meristem
(2)	Leaf primoridum	Short optical meristem	Axillary bud	Cork cambium
(3)	Axillary bud	Leaf primoridum	Shoot apical meristem	Differentiating vascular tissue
(4)	Axillary bud	Shoot apical meristem	Meristematic zone	Leaf primoridium

The correct option that represents the correct labeling of A, B, C, and D in the given figure is:

Option 3 (d)

Detailed Explanation:

1. A: Leaf primordium (1)
   • The leaf primordium is the early stage of leaf formation in the apical meristem of the shoot. It is the site of leaf initiation and development.
2. B: Meristematic zone (2)
   • The meristematic zone consists of actively dividing cells. These cells are responsible for the growth and development of new tissues in the plant.
3. C: Axillary bud (3)
   • The axillary bud is a structure that arises from the angle between the leaf and stem, capable of forming a branch or flower under appropriate conditions.
4. D: Intercalary meristem (4)
   • The intercalary meristem is found between mature tissues, usually in monocots, allowing for the elongation of stems and leaves.

Concept:

• The plant growth occurs in specific regions called meristems, where cells divide to form new tissues.
• The leaf primordium is where leaves start developing. The meristematic zone is where active cell division occurs.
• Axillary buds can form new shoots, and intercalary meristems allow for growth in regions between mature tissues.
