Mitosis Chapter 8 Cell Division

Binary Fission Another name for cell division in prokaryotes is binary fission. Cell splits in two.

Hemorrhagic E. Coli see the binary fission

Mitosis In Eukaryotic Cells the division of cells is called Mitosis. Formation of two identical daughter cells.

Mitosis Overview Mitosis Animation Mitosis Movie

Prophase Chromatin fibers coil to become dense chromatids They join at the centromere

Prophase Nucleolus Disappears Spindle Fibers Form as microtubules out from the centromeres Nuclear envelope begins to disintegrate

Prophase Centrioles now at opposite poles Note spindles stretched pole to pole

Metaphase Sister chromatids line up at the equator

Anaphase Spindle fibers pull the chromatids to the opposite poles

Telophase Chromatids are now at the opposite ends of the cell

Cytokinesis Separation of cytoplasm
