Answers
Explanation:
As a prerequisite for fertilization, pollination is essential to the production of fruit and seed crops and plays an important part in programs designed to improve plants by breeding. ...

Explanation:
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.
Key Terms
pollination: the transfer of pollen from an anther to a stigma that is carried out by insects, birds, bats, and the wind
heterostyly: the condition of having unequal male (anther) and female (stigma) reproductive organs
cross-pollination: fertilization by the transfer of pollen from an anther of one plant to a stigma of another
self-pollination: pollination of a flower by its own pollen in a flower that has both stamens and a pistil
