cell division

the splitting up of a cell into two new cells

Cell division

Celdeling

• Each chromosome in the nucleus is copied.
• Then, two nuclei (plural of Nucleus) are formed.
• Next, the cell divides.
• After that, cytoplasm growth occurs.

Cell division 

• During each cell division, the chromosomes are copied first.
• All the cells in your body contain the same genetic information.

Stem cells

Stem cells

When cells divide they don't really have a function yet. They can still turn into many different cells. These are called stem cells. After fertilizations, cells are made that can really become anything they want (making them super powerful). These are called embryonic stem cells.
