Question

Read the assertion and reason carefully to mark the correct option in question.
Assertion: A bud is present in the axil of petiole of both simple and compound leaves but not in the axil of leaflets of the compound leaf.
Reason: The stem bears buds, which may be terminal or axillary. The axillary bud later develops into a branch.

• A. If the assertion is true but the reason is false.
• B. If both assertion and reason are true and the reason is the correct explanation of the assertion.
• C. If both assertion and reason are true but reason is not the correct explanation of the assertion.
• D. If both assertion and reason are false.

Answer 1

The correct option is C If both assertion and reason are true but reason is not the correct explanation of the assertion.

Assertion-Reason relation
Axillary buds emerge from the axils of petioles of simple as well as compound leaves. The compound leaves consist of small leaflets which are separate, but these do not bear buds in the axils. The buds of compound leaves are present in the axil of the main petiole. Hence, the assertion statement is correct.

Assertion-Reason relation
The stems bear both vegetative as well as floral buds in terminal and axillary positions.

• The terminal vegetative buds help in growing the plant at the apex.
• The axillary buds help in lateral growth by giving rise to branches.
• The floral buds produce flowers.

Hence, the reason statement is correct but doesn’t justify the assertion.

Final answer: (b) If both assertion and reason are true but reason is not the correct explanation of the assertion.
