question 23

Essay

In mammals,an egg fertilized by one sperm divides repeatedly (1-2-4-8-16-32-64,etc.).At the 64-cell stage,only three cells go on to become the embryo while 61 grow to become the fetal side of the placenta.In plants,fertilization likewise results in the development of an embryo and nourishing endosperm.However,how does this process differ from the mammal embryo and placenta?
