Assertion:  Gynoecium consists of pistil.
Reason: It represents the male reproductive part in flowering plants.

Assertion is true but reason is false .

The correct answer is Option (1): Assertion is true but reason is false .

The gynoecium, also known as the carpel, is the collective term for the female reproductive organs within a flower. It is composed of one or more pistils. The pistil is the individual unit of the gynoecium, and it consists of three main parts: the stigma, style, and ovary.

The stigma is the receptive surface at the top of the pistil that receives pollen during pollination. The style is the slender elongated part that connects the stigma to the ovary. The ovary is the enlarged basal portion of the pistil that contains one or more ovules, which house the female gametes (eggs).

Together, these parts of the gynoecium play a crucial role in the female reproductive process of flowering plants, including pollen capture, pollen tube growth, fertilization, and seed development.

In summary, the gynoecium consists of the pistil, which represents the female reproductive part in flowering plants. The assertion is correct, but the reason provided is incorrect as it states that the gynoecium represents the male reproductive part, which is not the case.
