In angiosperms, what structure develops after a pollen grain germinates and carries the male gametes toward the ovule?
Answer and explanation
Correct answer: Pollen tube
When a pollen grain germinates on the stigma, it produces a pollen tube. The tube grows through the style and enters the ovule, eventually reaching the embryo sac and delivering the two male gametes. The embryo sac, integument, and style are separate structures and do not themselves transport the gametes.
