Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): In a flower, the gynoecium may consist of a single pistil or of more than one pistil.
Reason (R): The gynoecium represents the male reproductive part of the flower.
In the light of the above statements, choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) is true but (R) is false.
A flower has two reproductive whorls. The androecium, a whorl of stamens, is the male reproductive organ. The gynoecium, made of one or more pistils, is the female reproductive part.
Assertion (A): In a flower, the gynoecium may consist of a single pistil or of more than one pistil. — True. A gynoecium with a single pistil is monocarpellary; one with more than one pistil is multicarpellary.
Reason (R): The gynoecium represents the male reproductive part of the flower. — False. The gynoecium represents the female reproductive part. The male part is the androecium, which consists of stamens.
So A is true but R is false.

The Pistil, Megasporangium (Ovule) and Embryo Sac – “The gynoecium represents the female reproductive part of the flower. The gynoecium may consist of a single pistil (monocarpellary) or may have more than one pistil (multicarpellary). When there are more than one, the pistils may be fused together (syncarpous) (Figure 1.7b) or may be free (apocarpous) (Figure 1.7c). Each pistil has three parts (Figure 1.7a), the stigma, style and ovary.”
