Mitosis Mitosis is a 4-stage process in which two identical nuclei are created before cell division. Mitosis occurs in animal and plant cells, though there are some differences between the two.

Mitosis- Prophase Breaks down the nuclear envelope. Chromosomes (DNA) condense. Mitotic spindle formed. Centrioles move to sides.

Mitosis- Metaphase Chromosomes line up in the middle and attach to the (mitotic) spindle fibers.

Mitosis- Anaphase The spindle fibers shorten Chromosomes move to opposite poles.

Mitosis- Telophase The nuclear envelope reforms Chromosomes spread out Spindle fibers dissolve.

Cytokinesis Divides cytoplasm into 2 cells

Use the coloring code table to color each cell. Cell Cycle Matching Directions: Use the coloring code table to color each cell. Use your textbook to help you determine each stage. Cut & Paste each stage in the box on your note-taker.
