Question

One sperm cell fuses with the egg cell while another sperm cell fuses with two nuclei in one of the cells of the female gametophyte in the process of 
 fertilization.

BlackTom AI · Accepted Answer

The question describes a process in which one sperm cell fuses with the egg cell and another sperm cell fuses with two nuclei in a cell of the female gametophyte during fertilization. This matches the classic description of double fertilization in flowering plants, where one sperm forms a zygote with the egg, and the other sperm fuses with the two polar nuclei (in the central cell) to form the triploid endosperm."空白1" as an option is not informative or meaningful content; it does not specify the correct biological term. In contrast, the key concept here is double fertilization, which uniquely explains the two simultaneous fertilization events and the formation of both the embryo and the endosperm. Therefore, the proposed answer that should fill the blank would be the term "double fertilization." The option provided, literally labeled as 空白1, fails to convey this concept and does not identify the process; it would be considered incorrect for conveying the necessary terminology. Understanding why this is the correct concept helps clarify common confusion between fertilization events and other reproductive processes that do not involve two fertilization steps. Keeping in mind the distinction between the zygote formation and endosperm formation reinforces why double fertilization is the accurate description here.
