Answer 1

In a bisexual flower when the gynoecium matures earlier than the anthers, the phenomenon is called protogyny.

Explanation:

Protogyny is the condition in a bisexual flower where the gynoecium (female part) matures earlier than the anthers (male part). This temporal separation helps to prevent self-pollination and promotes cross-pollination by ensuring that the stigma is receptive before the pollen is released from the same flower.
