Mitosis

1
Mitosis

• Concept 9.3

2
Mitosis

• One cell with a full complement of chromosomes
  dividing into 2 new identical cells.

3
Mitotic Phases

• Prophase
• Metaphase
• Anaphase
• Telophase

4
Early Prophase

• Chromatin condenses into chromosomes
• Nucleolus disappears

5
Late Prophase

• Nuclear envelope breaks down
• Spindle forms
• Centrosome moves to opposite ends of the cell

6
Metaphase

• Chromosomes line up in the middle of the cell

7
Anaphase

• Sister chromatids separate and move closer to the
  poles
• Chromatids are considered chromosomes

8
Telophase

• Chromosomes reach spindle
• Nucleolus and Nuclear envelope reappear

9
Telophase

• Chromosomes uncoil into chromatin
• Cell begins to divide

10
Cytokinesis

• A cleavage furrow forms dividing the cell in two
• Plant cells are divided by a cell plate
