Answer:
Pollen germination starts with the pollen grain landing on stigma. ... The intine grows out through the germ pore and form pollen tube. It grows into the tissue of the style towards the ovary. By this time the tube nucleus degenerates and the generative nucleus divides to form two male gametesDuring germination, the tube cell elongates into a pollen tube. In the flower, the pollen tube then grows towards the ovule where it discharges the sperm produced in the pollen grain for fertilization. The germinated pollen grain with its two sperm cells is the mature male microgametophyte of these plants.
