Assertion (A): Buds present in the axils of leaves are capable of forming a branch or a flower.
Reason (R): Axillary buds are constituted by the shoot apical meristems.
To solve the problem, we need to determine the correctness of the assertion and the reason and their relationship.
1. Understanding the Assertion and Reason:
The assertion states: "Buds present in the axils of leaves are capable of forming a branch or a flower."
The reason states: "Axillary buds are constituted by the shoot apical meristems."
2. Analyzing the Assertion:
The assertion is correct because buds found in the axils of leaves can indeed form either a branch or a flower depending on the conditions and developmental signals.
3. Analyzing the Reason:
The reason is also correct. Axillary buds are formed from the shoot apical meristem, which is responsible for the growth of new shoots or branches.
4. Checking the Explanation:
The reason provides the correct explanation for the assertion. Since axillary buds arise from the shoot apical meristem and are capable of forming branches or flowers, the reason justifies the assertion.
Final Answer:
The correct answer is (A) A and R are correct. R is the correct explanation of A.
