Cell Division - Mitosis

Cell division forms new cells. Mitosis is one of two types of cell division.

• Produces two new cells, each having two sets of chromosomes.
• Produces all cells except reproductive cells.
• Produces cells identical to the parent cell.
• Results in the growth and repair of tissue.
• Occurs in five stages.

Interphase

• Cell involved in normal cell processes.

Prophase

• Each chromosome is copied.
• Chromosome pairs attached at middle.
• Nuclear membrane disappears.

Metaphase

• Chromosome pairs line up.
• Spindle fibers attach to the center of each chromosome pair.

Anaphase

• Spindle fibers pull apart the chromosome pairs.
• Two identical sets of chromosomes are pulled to either side of the cell.

Telophase

• Spindle fibers disappear.
• Nuclear membrane forms around each set of chromosomes.
• Cell membrane and cytoplasm pinch in to form two new identical cells.

Interphase

• Two new cells become involved in normal cell processes.
