Answer: Pollination, the transfer of pollen from flower-to-flower in angiosperms or cone -to-cone in gymnosperms, takes place through self-pollination or cross-pollination.
Cross-pollination is the most advantageous of the two types of pollination since it provides species with greater genetic diversity.
Maturation of pollen and ovaries at different times and heterostyly are methods plants have developed to avoid self-pollination.
The placement of male and female flowers on separate plants or different parts of the plant are also barriers to self-pollination.
