Question

In protandry, which reproductive structure matures first?

Options

• The androecium and gynoecium mature in reverse order

• Both mature simultaneously

• The androecium (anther)

• The gynoecium (stigma)

Answer 1

Protandry is a type of dichogamy where the androecium (anther) matures and sheds pollen before the stigma becomes receptive. This temporal separation prevents self-pollination by ensuring self-pollen is unavailable when the stigma is receptive.
