Student Name _________________________________ Cell Division Quiz Review 1. Define the following vocabulary. Draw a diagram if applicable. • DNA - The genetic material found in all living cells that contains the information needed for an organism to grow, maintain itself, and reproduce. • Chromosomes - The physical structure in a cell that contains the cells genetic material. • Interphase - The part of the cell cycle when a cell is not dividing but is carrying out its normal functions. This is not part of mitosis. • Mitosis - Part of the cell cycle that includes prophase, metaphase, anaphase and telophase. • Prophase - Step 1 in Mitosis. Chromosomes condense and the nuclear membrane disappears. • Metaphase - Step 2 in Mitosis. Chromosomes line up in the middle of the cell. • Anaphase - Step 3 in Mitosis. Chromatids splits apart and pull to the opposite ends of the cell. • Telophase - Step 4 in Mitosis. New nuclear membranes are formed. • Cytokinesis - Part of the cell cycle following mitosis where the parent cell's cytoplasm divides into two new cells. • Meiosis - A part of sexual reproduction in which cells divide to form sperm cells in a male and egg cells in a female. Meiosis occurs only in reproductive cells. 2. How is the function of cell division in single-celled organisms different from cell division in multicellular organisms? • Single-celled organisms use cell division for reproduction. • Multi-cellular organisms use cell division to replace injured or worn out cells. 3. List the four stages of mitosis. • Prophase, Metaphase, Anaphase, Telophase 4. Which stages of the cell cycle are not considered part of mitosis? • Interphase & Cytokinesis Student Name _________________________________ Cell Division Quiz Review 5. How are the offspring produced by asexual reproduction different from the offspring produced by sexual reproduction? • Offspring produced by asexual reproduction are genetically identical to their parent cells. • Offspring produced by sexual reproduction get half of their genes from each parent. 6. How does the number of chromosomes in a parent cell compare to the number of chromosomes in a daughter cell after mitosis? • The number of chromosomes in a parent cell is the same as the number of chromosomes in a daughter cell after mitosis. 7. During mitosis, how many times do the cells divide? • Cells divide once during mitosis. 8. During meiosis, how many times do the cells divide? • Cells divide twice during meiosis 9. Compare and Contrast Meiosis and Mitosis. Meiosis Mitosis • • • Sex Cells are Produced (sperm & egg) Divides twice Creates four identical daughter cells. • • • Starts with one parent cell Cells divide Both undergo DNA replication • • Divides once Creates two identical daughter cells.
