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 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:

  1. A
    Both A and R are true and R is the correct explanation of A
  2. B
    Both A and R are true but R is NOT the correct explanation of A
  3. C
    A is true but R is not false
  4. D
    A is not false but R is true

Solution & Step-by-step Explanation

Assertion A is correct: Morphologically, a flower is a highly specialized reproductive shoot.Reason R is correct: When the shoot changes to a flower, the internodes do not elongate, and the axis becomes condensed. The nodes then produce floral parts (sepals, petals, etc.) instead of typical foliage leaves.Since the condensation and modification of the shoot (R) is the morphological basis for calling the flower a modified shoot (A), R explains A.
