Cell Cycle, Mitosis, Meiosis

Cells spend most of their lives in which phase?

• Interphase

• Prophase

• Telophase

• Metaphase

What is cytokinesis?

• When 2 cells merge together to make 1 giant cell

• The end of the cell cycle when the cell divides and mitosis is complete

• The stage when DNA condenses into chromosomes

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

Why do cells go through mitosis?

• to make food from sunlight

• to get air into the cells

• to create proteins

• to reproduce, grow, and repair/replace cells

Daughter cells created by meiosis II have

• half the parents DNA

• exact copy of the parent's DNA

• twice the parent's DNA

• created their own DNA from scratch

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).

• Controlled cell division

• Unregulated cell growth and division
