Pollination is the process by which pollen is transferred in the reproduction of plants anther to stigma of same or different flower, thereby enabling fertilization and reproduction.
The study of pollination by insects is known as anthecology.
anemophily, is pollination by wind.
Hydrophily is pollination by water
Entomophily is pollination by insects
Anthropophily pollination by humans
Angiosperm means a plant that produces seeds within an enclosure; they are fruiting plants, although more commonly referred to as flowering plants.
Cross-pollination, also called allogamy, occurs only when pollen is delivered to a flower from a different plant.
Self-pollination, also called autogamy occurs when pollen from one flower pollinates the same flower or other flowers of the same individual.
How can you differentiate between self and cross pollinated flower?
Cross-pollinated flower often have taller stamens than carpels .
When the pollen of one flower pollinate the stigma of different flower but on same plant is called geitonogamy.
Cross pollination within species is called xenogamy.
Importance of Pollination
It is essential for survival of plants on earth. It leads to fertilization and production of seeds and fruits, which ensure continuity of plant life.
The role of pollination in the production of hybrid seeds has been of great significance.
The pollination, especially cross pollination results in the production of plants with a combination of characters from two plants. This helps to merge useful characters from two different plants into one
DIFFERENCE BETWEEN SELF AND CROSS POLLINATION
In self pollination, the pollen grains are transferred from anther to stigma of the same flower or different flower present on the same plant.
In cross pollination, the pollen grains are transferred from anther to stigma of another flower present on a different plant.
In self pollination, only one plant is involved.
In cross pollination, two different plants are involved.
It is a sure method of pollination (pollination rarely fails).
It is not a sure method of pollination (pollination may fail).
