Fertilization in plants is not directly influenced
by sunlight. It occurs when pollen grains are
transported from anthers to stigma. When ripe
pollen from an anther catches on the stigma of
the same kind of flower, each pollen grain sends
out a small thread-like tube. Fertilization occurs
after pollination, when pollen grains land on the
stigma of a flower of the same species. During
this time, a series of events take place leading to
the formation of seeds.
