What is the role of the pollen tubes in pollination?
What is the role of the pollen tubes in pollination?
To transport the male gametes to the egg cell
To provide nourishment to the developing embryo
To enter the embryo-sac and release the male gametes
To transport the diploid secondary nucleus to the ovule

Pollen tubes grow through the tissues of the stigma and style and reach the ovule, where they enter the embryo-sac and release the male gametes for fertilization.
