Answer 1

cross pollination:when the pollen grains from the anther of a flower lands on the stigma of a different flower it is called cross pollination. it takes place in both bisexual and unisexual flowers

self pollination:when the pollen grains from the anther of a flower lands on the stigma of the same flower it is called self pollination. it takes place only in bisexual flowers

that's it

Answer 2

Answer:

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.
