Answer 2

Answer:

$\pink{Self \: pollination \: vs \: Cross \: pollination\:}$

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.
