NEET BIOLOGY

Detailed explanation-1: -Geitonogamy is the type of self-pollination where the transfer of pollen grains from the anther to the stigma takes place between different flowers in the same plant. Though it seems like cross-pollination and takes place with the help of pollinators, both the gametes have the same plant as their origin.

Detailed explanation-2: -The transfer of pollen from stamens to stigma of the same flower or between two flowers of the same plant is called self pollination. The type of pollination taking place within two flowers of different plants is called cross pollination. The type of pollination also depends on the different pollinators.

Detailed explanation-3: -Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Detailed explanation-4: -Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms).

Detailed explanation-5: -plant breeding A flower is self-pollinated (a “selfer”) if pollen is transferred to it from any flower of the same plant and cross-pollinated (an “outcrosser” or “outbreeder”) if the pollen comes from a flower on a different plant.
