Question

Quizplus · Accepted Answer

Double fertilization is the process in which one sperm fertilizes the egg to form the zygote, while the other sperm fertilizes the polar nuclei to form the endosperm. This occurs in flowering plants (angiosperms), where the male gametophyte (pollen) contains two sperm cells. Therefore, fertilization of two eggs (option A and D) or fertilization of an egg by two sperm (option B) do not accurately describe double fertilization. Additionally, option E implies that the sperm fertilizes both the egg and the endosperm-forming cell, which is not possible as they are located in different parts of the ovule.
