NEET BIOLOGY

Detailed explanation-1: -Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.

Detailed explanation-2: -Through the process of meiosis, pollen is formed in the pollen sacs (microsporangia) inside the anthers of a flower. The anther, while it is developing from anther primordium (undifferentiated cells), forms two clusters of cells.

Detailed explanation-3: -Final answer: Pollen grains are produced in anther.

Detailed explanation-4: -Pollination is an essential part of plant reproduction. Pollen from a flower’s anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.

Detailed explanation-5: -Anthers are the male reproductive part of a flower. Stigma is the female reproductive part of a flower. The anthers are bilobed with sac-like structures (microsporangia) present inside them. The stigma is a receptive base on which the pollen lands.
