Question
Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R): Assertion (A): A flower is defined as a modified shoot wherein the shoot apical meristem changes to floral meristem. Reason (R): Internode of the shoot gets condensed to produce different floral appendages laterally at successive nodes instead of leaves.
In the light of the above statements, choose the correct answer from the options given below:
(A) is False but (R) is True.
Both (A) and (R) are True and (R) is the correct explanation of (A).
Both (A) and (R) are True but (R) is not the correct explanation of (A).
(A) is True but (R) is False.
, a flower is a modified shoot where the shoot apical meristem changes to floral meristem. Internodes do not elongate and the axis gets condensed. The apex produces different kinds of floral appendages laterally at successive nodes instead of leaves. This condensation of the internode and the production of floral appendages at successive nodes explain why the flower is considered a modified shoot.
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Morphology of Flowering Plants. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
