The snowdrop is an example of a self-destructive flower.
In self-pollination or autogamie, pollen is transferred to the stamp of the same flower. In neighboring pollination (goatonogamy), pollen occurs on another flower, which is on the same plant, which results in self-pollination. Cleistogamie is a special form of self-pollination, with the flower not even opening.
Pollination and fertilization are often intertwined. Pollination can lead to fertilization but that does not have to. After pollination, the sperm cells from the pollen grain must be brought into the eggplant via the pollen tube and the fusion should melt together. In the air there are many different pollen grains and only a specific combination of pollen grain and stamp gives fertilization.
Self-fertilization has the advantage that it makes the plant independent of its pollinators. It allows plants to grow where flying insects are rare, such as in the high mountains, in windy or very shady places. With successful self-fertilizers, it can lead to a rapid increase in the number of plants, but by suppressing the gene exchange also to the isolation of the population. Ultimately self-pollination can lead to species or speculation.
Self-pollination occurs frequently in orchids, such as wasps and bushes. Self-fertilization
Self-fertilization also occurs in fungi. Homothalous fungi can reproduce sexually with the same species of fungal sprays. The mycelium forms different cells with male and female reproductive organs, and self-fertilization can occur. Also see WikiWoordenboek
