In eukaryotes there is a nucleus, so a more complex process called mitosis is needed with cell division. Mitosis is divided into four parts, or phases:
Phase 1 – Prophase: In this phase the nuclear membrane begins to break down and the DNA forms structures called chromosomes.
Phase 2 – Metaphase: In this phase the chromosomes line up along the center of the parent cell
Phase 3 – Anaphase: In this phase, the chromosomes break apart, with a complete set of DNA going to each side of the cell
Phase 4 – Telophase: In this phase, a new nuclear membrane forms around each of the sets of DNA
The four stages of mitosis (the cell at the top has not started mitosis) lead to two daughter cells.
A little after telophase, the cytoplasm splits and a new cell membrane forms. Once again, two daughter cells have formed. Take a look at this animation for a good overview of mitosis and see if you can identify all the phases.
