Understand the Cell Cycle and Mitosis

You are much bigger today than you were when you were born because . . .

• parts of your body stretched out as they filled with food

• you are made of more cells today than at birth

• your cells are now much bigger than baby cells

Compared to the parent cell, each daughter cell is. . .

• genetically different (different number of chromosomes and different genetic info)

• genetically identical (same number of chromosomes and same genetic info)

Mitosis is important because . . .

• it takes place in 4 distinct stages

• ensures genetic continuity in all cells of an organism

• provides energy for a cell
