Question

what stigma and anthers do not grow up to same height, which favours only cross pollination?

Answer 1

The transfer of the pollen grains from the anther of the plant to the stigma is referred to as the process of pollination.

The pollen grains are immobile in nature and hence cannot move by itself.

An external agent such as water, wind or even birds and insects are required for the transfer of the pollen grains.
