Question

define pollination and write its types.​

Answer 1

Answer:

Pollination is the process of transfer of pollen grains from anther to stigma. The two types of pollination found in flowering plants are: Self pollination: that occurs within the same plant. Cross-pollination: that occurs between two flowers of two different plants but of the same kind.

Answer 2

Pollination is the deposit of pollen grains on the stigma of a flower by anthers from the same flower, the same plant, or a separate plant.

Two forms of pollination exist.

• Stigma receives pollen grains from the same flower, which is known as self pollination.
• Stigma receives pollen grains from a flower on the same or a different plant during cross pollination.
• Anemophily and Entomophily, respectively, are two pollination agents.
• Grasses, Gymnosperms, and other wind pollinated plants
• Roses, Euphorbia sps, and other examples of insect pollination
• Pollination and fertilization - Appropriate pollination results in suitable pollen grains being deposited on the stigma, which leads to the production of pollen tubes and fertilization.
