NEET BIOLOGY

Detailed explanation-1: -The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen. The bottom of the pistil contains the ovary and the narrowed region in between is called the style.

Detailed explanation-2: -Sexual reproduction requires genetic material ( DNA ) from two parents. The parent plants have male and female sex cells, called gametes. The genetic material from the male and female gametes combines to produce offspring.

Detailed explanation-3: -A bisexual flower has both the male and the female reproductive parts. The male gametes are found inside the pollen grains and female gametes are found in the ovule. Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of the same or another flower.

Detailed explanation-4: -The corolla: zero or more whorls of petals above the calyx. The androecium: zero or more whorls of stamens, each comprising a filament and an anther. The gynoecium: zero or more whorls of carpels, each consisting of an ovary, a style, and a stigma.
