explain herkogamy, heterostly, self sterility and dichogamy
Answers
Answer:
Herkogamy is a type of mechanism employed by flowers (angiosperms) to encourage cross pollination over self-pollination. ... On the other hand, heterostyly is a form of herkogamy, where the stigma grows at a different length with the anthers such that they cannot get fertilized by them.
THE term 'self-sterile' is used for describing plants which fail to set self-seed when they are grown in isolation or when they are self-pollinated. ... This membrane is ruptured by artificial self-pollination or by insect pollination of the flower, after which pollen can germinate and grow.
Dichogamy is the process of maturation of the anthers and the stigma of a flower. The maturation occurs at different times in different plants. Protandry is when the anthers are the first to mature in the flowers of the plant. ... Protandry occurs in the flowers of Jasmine, Sunflower, etc.
