How does pollination result in fertilization?
Pollination is the transfer of pollen grains from an anther to a preconception. Pollen can be moved by an animal or by the wind. Fertilisation occurs inside the ovary when the nucleus of pollen grain merges with the nucleus of an ovule to produce a zygote
What are the actions of pollination?
- Pollen grains arrive at the sticky preconception.
- A pollen tube grows down the design, followed by male sperm nuclei.

How does fertilization happen in flowers?
From the anther the pollen grains are very first transferred on the pistil’s surface area, the preconception. There they sprout and form pollen tubes, which grow downward through the design towards the ovules. Fertilization takes place as a sperm cell in a pollen tube merges with the egg cell of an ovule, leading to a plant embryo.
How do plants avoid fertilization?
In types in which staminate and pistillate flowers are discovered on the very same person (monoecious plants) and in those with hermaphroditic flowers (flowers having both endurances and pistils), a typical method of avoiding self-fertilization is to have the pollen shed either prior to or after the duration throughout which the …
