Which mechanism prevents an ovum from being fertilized by multiple sperm cells? A. Once a sperm penetrates the jelly-like coating of the egg, no other sperm cell can penetrate the coating. B. When a sperm fuses with the plasma membrane of the egg, depolarization of the membrane occurs. C. The egg can survive in the Fallopian tube for 24 hours s it does not have mitochondria to produce energy. D. When more than a single sperm cell fuses with the plasma membrane, multiple zygotes can form, leading to the twin or triplets.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
