A:
Triple Fusion
B:
Fusion Of One Male Gamete With Egg And Another Male Gamete With Two Nuclei Of Central Cell
C:
Fusion Of One Male Gamete with And Egg
D:
Fusion Of Two Male Gamete With Egg To Form Endosperm Nucleus
Explanation
The correct answer is:
B: Fusion Of One Male Gamete With Egg And Another Male Gamete With Two Nuclei Of Central Cell
Double fertilization is a unique feature of angiosperms (flowering plants) in which two male gametes (sperm cells) from the pollen tube fertilize two different cells in the female gametophyte (embryo sac) inside the ovule.
One sperm cell fuses with the egg cell to form the zygote, which develops into the embryo, and the other sperm cell fuses with two polar nuclei in the central cell to form the triploid endosperm nucleus, which develops into the endosperm that provides nutrition to the developing embryo. This process is called double fertilization because it involves the fusion of two haploid nuclei (sperm and egg) and three haploid nuclei (two polar nuclei and one sperm).
