Question

The female reproductive organs in a flower is
A. Sepals
B. Petals
C. Stamens
D. Carpels

Answer 1

Hint:The female reproductive portion of the plant, consisting of an ovary, stigma, and style, is divided into three distinct sections and helps in the fertilization process. Each of the units is classified as megasporophyll or carpel.

Complete answer:
The gynoecium is seen on whorl number four. The unit is classified as megasporophyll or carpel. It is made up of ovaries, stigma, and style. It is the flower's female reproductive organ. The ovary is an expanded basal part that can be found above or below the base of the petals and sepals or at the point of junction with them. A locule is a chamber that produces the ovules in it. The style is a pillar-like stalk from which the ovary is penetrated by pollen tubes.

 Some flowers do not have a distinct form, such as tulips, and the stigma sits directly on the ovary. Whereas the style is a hollow tube in some plants such as lilies or has transmitting tissues from which the pollen tubes emerge. Stigma is normally located at the tip of the style that receives pollen or gametophytes from men. They are sticky to trap pollen or are feathery. The stigma is a carpel's top and sticky part. It is a pollination site. The carpel type is a long tube connecting the stigma to the ovary. The lowermost portion of the carpel is the ovary and includes the ovules.

Hence the correct answer is option D-Carpels.

Note: A megasporophyll is a megasporangia-like structure. Each pistil is composed of one or more enrolled carpels, each containing one or more ovules. A single megasporophyll is a carpel. There are separate pistils (and thus separate carpels) in an apocarpous flower, whereas a syncarpous flower comprises a single pistil with two or more united carpels, referred to as syncarpous.
