Solution

Adaptations required by self-pollinated plants are:
(i) Bisexuality - Self-pollination occurs only in bisexual flowers.
(ii) Homogamy - Both anther and stigma need to mature at the same time.
(iii) Cleistogamy - Flowers which are bisexual and never open are called cleistogamous flowers. They are small, colourless, odourless and without nectar. The pollen grains fall on the stigma inside the closed flower. Example - Arachis
