Why do we need the cell cycle?
• The cell cycle ensures that the number of chromosomes in body cells always remains constant.
• Chromosome # varies based on species:– Dogs = 78– Tomatoes = 24– Humans = 46
Making a Graph
• Both the x and y axis need a label• Both the x and y axis need units• The graph needs a title• Data points should be visible and neat
Normal Cell Replacement
• Cells don’t live forever, must be replaced
• Die when the cell receives instructions to do so
• Mitosis and cell division replace dead cells
Regeneration•Repair of injured cells or the making of lost body parts.
