- How does double fertilization occur in flowering plants?a. The two sperm in a pollen tube fertilize the two egg cells present ineach female gametophyte.b. One of the two sperm in a pollen tube fertilizes the single egg in afemale gametophyte, and the other fuses with the two nuclei presentin the central cell.c. Two sperm, one contributed by each of two different pollen tubes,fertilize the two egg cells in a single female gametophyte.d.
