The purpose of Mitosis (cell division) is to:
create more cells for the body.
Why do we need to do this?
repair, growth, replacement
Mitosis produces:
2 identical daughter cells (each with the same exact genetic information)
The cell divides once.
Meiosis:
Reproduction division in which the # of chromosomes is cut in half by separation of homologous chromosomes
Meiosis:
Reproduction division in which the # of chromosomes is cut in half by separation of homologous chromosomes
Why do we want to do that??
To create cells used in
