NEET BIOLOGY

Detailed explanation-1: -Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

Detailed explanation-2: -Due to the spatial separation between male and female pollen grains from the anther of most flowering plants, including orchids, pollens are transported by wind or animals and deposited onto the receptive surface of the stigma of a different plant.

Detailed explanation-3: -autogamy. If the pollen is transferred to the stigma of the same flower, it is termed as autogamy.

Detailed explanation-4: -As pollinators reach for the nectar in flowers, they rub against the pollen and it often sticks to them. As they move between flowers, the pollinator brushes off onto other flowers. This is a strategy plants use for pollen to travel and fertilization to occur, since plants are rooted in place.

Detailed explanation-5: -To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant’s stamen is transferred to that same plant’s stigma, it is called self-pollination. When pollen from a plant’s stamen is transferred to a different plant’s stigma, it is called cross-pollination.
