5. Which cell types undergo Mitosis?Prokaryotes: ______ Eukaryotes: _____Stages of Mitosis (PMAT)1. Prophase- chromosomes condense, nuclear envelope breaks apart2. Metaphase- chromosomes line up in center of cell3. Anaphase- chromosomes split apart to opposite ends of cell4. Telophase- nuclear envelope surrounds chromosomes

8. Division of Prokaryotes
9. Cell Cycle: When does division occur?90% cell Life
10. Cell Cycle Cell spends majority of life (90%) in Interphase (G1, S and G2)G1: cell growth, cell enlarges in size, continues to make and recycle organelles, etc. S: cell’s DNA is copied G2: cell prepares for nucleus to divideM: cell divides into two daughter cells Cytokinesis: cytoplasm and new cell membrane/ cell wall are made
