1. Eukaryotic Cell Reproduction
Interphase, Mitosis, and Cytokinesis

2. Interphase
Cell is carrying out all life functions

plus storing energy for mitosis
Each chromosome is duplicated which

forms chromatids
Chromatids: identical copies of a

chromosome, held together at
centromere

3. Prophase
1st phase of Mitosis

Nuclear membrane dissolves

Chromosomes condense and start to

move towards center of cell
Centrioles move to opposite sides of cell

Mitotic spindle fibers form between the

centrioles

4. Metaphase
2nd Stage of Mitosis

Mitotic spindle fibers attach to the

centromeres of each pair of
chromosomes
The chromosomes are lined up along

the equator of the cell

5. Anaphase
3rd Stage of Mitosis

Chromatids separate at the

centromere
Each chromatid is pulled to a pole of

the cell by the mitotic spindle fibers

6. Telophase
Last Stage of Mitosis

Nuclear membranes form around the

two sets of chromosomes
Chromosomes unwind

Mitotic fibers disappear

Mitosis is now complete


7. Cytokinesis
Eukaryotic cells without a cell wall, cell

membrane pinches inward and
eventually all the way through to form
the two daughter cells
In eukaryotic cells with a cell wall, a

cell plate forms in the middle of the
cell to divide the two cells.

8. What Did You Learn?
How are binary fission and mitosis

similar? How are they different?
Why is it important for chromosomes

to be copied before cell division?
What would happen if cytokinesis

occurred without mitosis?
