This is the process whereby cells reproduce by cell division?

Every cells reproduces by dividing itself.

The cells in the human body reproduces in two different ways, mitosis and meiOSis.

Mitosis is the cell reproduction in which the cell divides to create two off-springs with the same genes.

MeiOSis is the kind of cell reproduction in reproductive cells such as sperm. In which the mother cell divides in half and creates two off-springs with different genes, then those two off-springs dived again.
