What is pollination?
The transfer of pollen from a stamen to a pistil; fertilization in flowering plants. It takes place through self-pollination or cross-pollination. Please note that this answer refers specifically to the pollination of angiosperms and gymnosperms.
Self-pollination:
Please see the related link below.
Cross-pollination:
The process in which the pollen from the anther of the male flower of a plant comes into contact with the ovary of a female flower from another plant, resulting in pollination.
Some methods/agents of cross-pollination are:
- Humans (cultivation)
- Insects (known as entomophily)
- Wind (known as anemophily)
- Animals (birds, bats)
Insects were separated from animals, because of the difference in pollination method.
Cross-pollination only occurs between species of closely related plants; for example, between different varieties of apple. Cross-pollination does not occur between unrelated plant genera, such as between an apple and an orange.
For further elaboration on the methods of cross-pollination, see the related links section. Pollination is the transfer of the pollen grains from the anther to the stigma of a plant.
What are the two main types of pollination?
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
