Question

In bud pollination anthers and stigma ripe before the opening of the buds, hence self-pollination takes place, e.g. pea, wheat, rice, etc. What are the advantages of autogamy?

Answer 1

Hint:In autogamy plants do not rely on external pollination factors and even smaller amounts of pollen grains produce a good rate of pollination success.

Complete answer:
The fusion of two gametes, which come from a single human, refers to self-fertilization. Autogamy is primarily used as self-pollination, a method of reproduction used by many flowering plants. However, protist species were also observed with autogamy as a reproductive means. Flowering plants participate frequently in autogamy, while the autogamy protists only participate in stressful conditions. Self-pollination, which is present in flowering plants, is an example of autogamy. Self-pollination takes place when the sperm in pollen from the plant stamen enters the carpets of the plant and fertilizes the present egg cell.

The major benefits of self-pollination are as follows:
1) It is important for some plants not to be dependent on pollinating agents.
2) The flower may pollinate a very small number of pollen grains.
3) Race pureness is preserved.
4) Self-pollination stops pollen grains from being wasted.
5) Less probability of pollination failure.
6) The genes are not diverse and therefore the pureness of the race is retained.

Note:Autogamy is the process to create gametes by the division of a single mother cell. In single cell organisms like the Paramecium protozoan, it is also found. But these species can also replicate by conjugation, by the exchange of genetic material, where cross-fertilization is accomplished.
