Pollination
Pollination
Pollination (/ˌpɒlɪˈneɪʃən/) is a process in which pollen is transferred from the male parts of a flower (the anther) to the female parts (the stigma) of either the same flower or another flower. This process is crucial for the fertilization of many types of plants, leading to the production of seeds and fruit.
Etymology
The term "pollination" comes from the Latin word "pollin-", which means "fine flour". This is a reference to the fine, powdery nature of pollen.
Process
Pollination can occur in several ways. In self-pollination, the pollen from the anther of a flower is transferred to the stigma of the same flower. In cross-pollination, the pollen is transferred from the anther of one flower to the stigma of another flower. This can occur through various means, including wind, water, and animals such as bees and birds.
Types of Pollination
There are two main types of pollination: abiotic pollination and biotic pollination. Abiotic pollination refers to pollination that occurs without the aid of living organisms, such as wind or water. Biotic pollination, on the other hand, involves the transfer of pollen by animals, particularly insects and birds.
