Pollination is an important step in the
reproduction of
seed plants. In
the angiosperms the pollination is the transfer of
pollen grains (male
gametes) from their
point of origin in the
anther to the to the
receptive surface of the
carpel called a
stigma.
(and from the microsporangium to the pollen
chamber of conifers and cycads) Pollen may be transferred to the
same or a different
flower to ensure the
fertilization of the
ovules (female
gametes)
to produce
seeds;
The successful cross-pollination process is realized by means of
various biotic or
abiotic
pollinator agents that
bring or move the pollen grains from the anther to the receptive part of
the
flower's carpel.
The main methods of pollination are:
Floral peculiar characteristics
associated with pollination by means of various pollinators are called
pollination syndromes.
