What is cytokinesis?

• When 2 cells merge together to make 1 giant cell

• The end of the cell cycle when the cell divides

• The stage when DNA condenses into chromosomes

• The stage where chromosomes are pulled to opposite ends of the cell.

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.

What is a difference between mitosis and meiosis? Mark ALL that apply!

• Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.

• Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.

• Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.

• Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).
