Pollination意思
Pollination is the process by which pollen grains are transferred from the male reproductive structure of a plant to the female reproductive structure of the same or another plant of the same species. This process is essential for the reproduction of most flowering plants and some other plant groups, as it leads to fertilization and the production of seeds and fruits.
There are two main types of pollination:
-
Self-Pollination: This occurs when the pollen from the anther of a flower lands on the stigma of the same flower or another flower on the same plant. It can happen either through wind, water, or by the action of pollinators such as bees, butterflies, and birds.
-
Cross-Pollination: This is the transfer of pollen from the anther of a flower on one plant to the stigma of a flower on another plant of the same species. Cross-pollination is often facilitated by pollinators and can lead to genetic diversity in the offspring.
Pollination is a vital part of the ecosystem, as it helps in the production of fruits and seeds, which are an important food source for many animals. It also helps in the maintenance of plant species and biodiversity.
