1
4 phases of nuclear division (mitosis), directed by the cell’s DNA (PMAT)
Prophase Metaphase—(Middle) Anaphase—(Apart) Telophase—(Two) Draw this!
2
Prophase Chromosomes coil and become visible
Centrioles (or poles) appear and begin to move to opposite end of the cell. Spindle fibers form between the poles. Nuclear membrane disappears. Prophase
3
Metaphase Chromosomes line up in the middle of the cell on the spindle fibers.
5
Anaphase Chromosome copies divide
Spindle fibers pull chromosomes to opposite poles
7
Telophase Chromosomes uncoil Nuclear membrane reforms
2 new nuclei are formed Spindle fibers disappear
9
Stage 3: Cytokinesis Cytoplasm and cell organelles divide evenly
Two new cells are formed No cell wall: cell pinches in two Cell wall: cell plate forms to separate the cells
