Mitosis
MITOSIS
Mitosis The part of cell division which results in two identical daughter cells from a single parent cell.
Mitosis can be divided into stages • Interphase • Prophase • Metaphase • Anaphase • Telophase • Cytokinesis
Interphase The cell prepares for division • Animal & Plant Cell – DNA replicated (copied) – Makes new organelles (synthesis) – Cell increases in size (growth)

Prophase The cell prepares for nuclear division • Animal & Plant Cell – Chromosomes form from chromatin – Centrioles separate & spindles form – Nuclear membrane disappears – LONGEST phase in mitosis
Prophase Animal Cell Plant Cell Photographs from: http: //www. bioweb. uncc. edu/biol 1110/Stages. htm
Metaphase: The cell prepares chromosomes for division • Animal & Plant Cell – Chromosomes line up at the middle of the cell – Spindle fibers attach to chromosomes at the centromere – SHORTEST phase of mitosis

Anaphase The chromosomes divide • Animal & Plant Cell – Spindle fibers pull chromosomes apart – ½ of each chromosome (called chromatid) moves to poles of cells

Telophase The cytoplasm divides • Animal Cell – DNA uncoils & appears as chromatin again – 2 nuclei form – Cell membrane pinches in to form the 2 new daughter cells • Plant Cell – DNA uncoils & appears as chromatin again – 2 nuclei form – New cell wall forms between two nuclei to form the 2 new daughter cells
