Cell division is the method of
Increasing the number of cells
Multicellular organisms require cell division for
Growth and repair
One parent cell =
Two daughter cells
All cells must have the same number of what as the original cell?

What isn’t lost in mitosis?
Genetic information
What is the first stage of mitosis?
Chromosomes start to become visible
What’s the second stage of mitosis?
Chromosomes replicate becoming pairs of chromatids
What’s the third stage of mitosis?
Spindle fibres form and chromosomes move to the equator of the cell
What’s the forth stage of mitosis?
Chromatids are pulled to opposite ends of the cell
What’s the fifth stage of mitosis?
The nuclear membranes form
What’s the sixth stage of mitosis?
