Following statements are regarding to double fertilization in angiosperms.
A. One sperm cell fuses with the egg cell to produce the zygote that will develop into the new embryonic plant.
B. The second sperm cell fuses with the usually binucleate central cell, giving rise to the
endosperm, the tissue that nourishes the developing embryo. This second event is not “true” fertilization in the sense of male and female gametes undergoing fusion.
C. The second sperm cell fuses with the usually binucleate central cell, giving rise to the
endosperm, the tissue that nourishes the developing embryo. This second event is “true” fertilization in the sense of male and female gametes undergoing fusion.
D. During fertilization in angiosperm, when the sperm cells are released, the egg undergoes a flux of Ca2+. Then, chemicals released from the egg appear to make the sperm competent for cell fusion.
