Cell Division - Mitosis and Meiosis

Mitosis in plants is different from mitosis in animals because 

• the nuclear membrane reforms in plants but not animals. 

• chromosomes are replicated in plants but not animals.

• replicated chromosomes separate in plants but not animals.

• a cell plate divides the cytoplasm in plants but not animals.

When sperm and egg are produced, they are in a haploid condition meaning

• they each have one half the number of chromosomes.

• they each have double the number of chromosomes.

• they each have quadruple the number of chromosomes.

• science has yet to determine the number of chromosomes.
