Why do plants release large number of pollen grains?

Answer 1

There are a lot of adaptations, and they are different depending on how the plant is pollinated. For example in wind pollinate species, the anthers hang out of the flower so they can get dispersed by the wind, the pollen is usually smooth or has air sacs and the stigma is feathery to increase the surface area and also hangs out of the flower.

In animal pollinated species, the anthers are usually prominently displayed so the pollinator can find them, the pollen is spiky so it can attach to the pollinator and the stigma is located somewhere the pollinators can get to it and is sticky. These are just generalizations and there are many variations on this theme.

Answer 2

Pollen grains are found on the stamen(male part)of the flower.They may be dispersed by insect pollination where insects help in taking pollen to other carpels or by wind pollination where the wind does so.

Answer 3

Plants release large numbers of pollen grains to increase the likelihood of successful pollination. By producing a high quantity of pollen, plants enhance the chances of the pollen reaching a compatible female reproductive structure for fertilization. This strategy helps ensure genetic diversity and reproductive success in plant populations.

Answer 4

To ensure the transfer of a compatible pollen on the stigma of another flower by any of the agencies of pollination i. e. wind, insect, bird or animal etc.
