3.      Restoration of nucleus to cytoplasmic ratio

4.     Continuation of cell growth

Which of the following cells are not constantly replaced?

The specialized kind of cell division that reduces the chromosome number by half results in the production of haploid phase in the life cycle is

1.      Meiosis

2.      Mitosis

3.      Amitosis

4.     Karyomitosis

Meiosis does not involve
