What is Pollination?
授粉is the process of transferring pollen from anthers to stigma of flowers. The process of pollination was actually discovered in the 18th克里斯蒂安·斯普伦格尔(Christian Sprengel)的世纪。有两种类型的授粉:self-pollination or cross-pollination. Self-pollination occurs within the same flower while cross-pollination occurs between two flowers of different plants.
Self-pollination produces genetically identical offspring while cross-pollination produces genetically different offspring. Hence, cross-pollination is more favored than self-pollination. Plants show different adaptations in order to prevent self-pollination and enhance cross-pollination. Once pollination occurs, the sperm cell travel to the egg cell and fertilization occurs. This completes the sexual reproduction of flowering plants.
什么是受精?
Fertilization is the union of male and female gametes in order to produce an offspring. The female egg will be fertilized by a male sperm and this will lead to the creation of a child, be it for animals or for plants.
For flowers, this only happens after a successful pollination and when there is a successful fusion of male and female gametes. Seeds are the result of fertilization of plants. Seeds then give rise to new plants. Fertilization is an internal process, unlike pollination.
What are the Similarities Between Pollination and Fertilization?
- Both pollination and fertilization occur in flowering plants.
- They are very important processes with respect to reproduction.
What is the Difference Between Pollination and Fertilization?
授粉是花粉从花药转移到花朵的污名,而受精是男性和女配子在有性繁殖中的融合。最重要的是,授粉仅适用于开花植物,而受精于这个世界上几乎所有生物体。在开花植物中,受精是授粉之后的过程。
In addition, pollination can be an external process while fertilization is always an internal process. Moreover, pollination, epically cross-pollination requires pollinators whereas fertilization has no need of pollinators.
概括– Pollination vs Fertilization
授粉is just the process of transferring the pollen to the stigma. This can be done through either self-pollination or cross-pollination. Cross-pollination is when there are outside agents like animals, people or the wind, to facilitate the transfer of pollen to stigma. While pollination only applies to flowering plants, fertilization applies to almost everyone in nature. Most importantly, there can be no fertilization if there is no pollination. This is the difference between pollination and fertilization.
