Explain about the two agents and methods of cross pollination with examples.
Answers
Pollination: Is defined as the deposition of pollen grains on the stigma of a flower from anthers belonging to the same flower, same plant or a different plant.
Pollination is of two types
Self pollination - Stigma receiving pollen grains from the same flower
Cross pollination - Stigma receiving pollen grains from a flower on the same plant or a different plant
Wind and insects are two agents of pollination, called as Anemoplily and Entomophily respectively
Example of wind pollination - Grasses, Gymnosperms etc
Example of insect pollination - Rose, Euphorbia sps etc
Pollination and fertilization - Suitable pollination leads to compatible pollen grains being deposited on the stigma, leading to pollen tube development and fertilization.
