PPT-0 Plant Diversity II: The Evolution of Seed Plants

The reason that two sperm nuclei travel down the pollen tube is that they both stimulate growth of the pollen tube one fertilizes the egg and the other combines with the two polar nuclei one fertilizes the egg .

A: Adaptations include 1)a reproductive process that takes place in cones or flowers, 2)the transfer of sperm by pollination, and 3)the protection of embryos in seeds.
