Question

In seed plants, how are non-motile male gametes transported to the female gamete?

Options

• They swim through the female reproductive tract

• They are dispersed by water currents

• They travel through the embryo sac independently

• They are carried to the female gamete by pollen tubes

Answer 1

In seed plants, the non-motile male gametes are carried to the female gamete by pollen tubes. Since these male gametes cannot move on their own, the pollen tube acts as a delivery mechanism from the pollen grain to the ovule.
