Question

The transfer of pollen grains from the anther to the stigma of the same or another flower of the same kind is known as -----

Answer 1

Hint:The main aim of all living organisms is the development of offspring. Stamen, which produces a sticky powder-like substance called pollen, is the male reproductive component of the flower. The female reproductive component of the flower is the pistil, and the sticky stigma is present on top of the pistil. This method is the sexual mode of reproduction carried out by the flowering plants of the kingdom of plants.

Complete answer:
Pollination is the process of transfer of pollen grain from the anther to the stigma of a pistil. It is a process by which male and female non-motile gametes are mixed for fertilization.
Pollination is called self-pollination in which pollen grains from the anther fuse with the stigma of the same flower, or with the stigma of another flower but of the same plant.

There are two forms of Self-Pollination: Autogamy and Geitonogamy. The transfer from the anther of one flower to the stigma of the same flower of the same plant of the pollen grains is called autogamy. Geitonogamy is called the movement of pollen grains from an anther of one flower to the stigma of another flower of the same plant. This transition requires a pollination agent. Genetically, as the pollen grains are derived from the same plant, it is similar to autogamy.
Cross-pollination is the movement of pollen from one flower's anther to another flower's stigma to another individual of the same species.
So, the correct answer is, ‘Pollination’.

Note: There is no variability in the genes in self-pollination, and thus the purity of the race is retained. Plants do not rely on external pollination stimuli, and even smaller amounts of pollen grains provide a good rate of pollination success.
In certain cases, pollination utilizes both biotic and abiotic agents such as wind, water, insects, birds, animals, and other agents as pollinators.
