Biology Question on Anatomy of Flowering Plants
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 node instead of leaves.
In the light of the above statements, choose the correct answer from the options given below:
Both A and R are true but R is NOT the correct explanation of A
A is true but R is false
A is false but R is true
Both A and R are true and R correct explanation of A
Both A and R are true and R correct explanation of A
Solution
Assertion A is true. A flower is indeed defined as a modified shoot in which the shoot apical meristem changes to floral meristem, leading to the formation of reproductive structures.
Reason R is also true. In a flower, the internode of the shoot is condensed, and this condensed region gives rise to different floral appendages (such as sepals, petals, stamens, and carpels) laterally at successive nodes instead of producing leaves. This phenomenon is a key characteristic of floral development.
Therefore, The correct option is (D): Both A and R are true and R correct explanation of A
