• interphase
• anaphase
• prophase
• telophase

• blood cells
• skin cells
• nerve cells
• stomach cells

How is cancer related to cell division?

• Mutations can cause uncontrolled cell division which causes cancerous cells to spread rapidly and take nutrients from healthy cells.

• Cancer stops cell division from happening.

• Cell division causes viruses that spread around the body and cause cancer.

• Cancer is not related to cell division.

What is "crossing over"?

• The exchange of genes between chromosomes during meiosis that results in genetic diversity.

• Programmed cell death (cell suicide) to prevent the spread of mutated/cancerous cells.

• A type of cell division that creates gametes (sperm and egg cells).

• A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent cell.
