Q.
Contrivances for self pollination are
Sexual Reproduction in Flowering Plants
Solution:
Contrivances for self pollination are bisexuality, homogamy and cleistogamy. In homogamy, the two sexes mature at the same time, there are good chances for self pollination. In bisexuality male and female flower are present on the same plant which also enhance self pollination. In cleistogamy when the flowers remain closed self pollination is the rule.
