Question

Differentiate between self-pollination and cross pollination.

Answer 1

Hint: Self-pollination is a pollination process that does not require an investment from the plant to provide pollinators with nectar and pollen as food. Typically, cross-pollination is carried out with the assistance of insects and wind.

Complete answer:
Pollination takes two forms: self-pollination and cross-pollination.

Self-Pollination	Cross-Pollination
Self-pollination occurs when the pollen of the anther, or another flower of the same species, is deposited on the stigma of the same flower.	Cross-pollination is the movement of pollen from one flower's anther to another flower's stigma to another of the same species' separate individuals.
In the same flower or in another flower of the same plant, this process may take place.	This process can take place between two flowers on different plants that are present.
Few self-pollinating species are Paphiopedilum parishii, Arabidopsis thaliana.	Few cross-pollinating species are apples, daffodils, pumpkins, and grasses.
Self-pollination increases the uniformity of genetics and reduces genetic variation.	Cross-pollination reduces the uniformity of genetics and increases genetic variation.
Both the stigma and the anther mature simultaneously in self-pollination.	Both the stigma and the anther ripen at different times in cross-pollination.
Pollinators are not required to transfer pollen grains.	Pollinators are required for the transfer of pollen grains.

Note:
In all plants, pollination is the sexual method of reproduction by the process of transferring the pollen grains from the anther to the gynoecium stigma and thus allowing the fertilization process. In this phase, just like all other living organisms, the spermatophytes or seed plants pass their genetic information to their next generation. In the 18th century, Christian Konrad Sprengel first identified the pollination process. This is commonly known as the interaction between a flower and a pollen vector. In agriculture and horticulture, the significance is found.
