| Question | Answer |
|---|---|
| 1.What is mitosis? | It Is the first stage of cell division. |
| 2. What is cytokinesis? | It is the second stage of cell division. |
| 3. What happens during the G1 phase? | Cell growth |
| 4. What happens during the S phase? | DNA replication. |
| 5. What happens during the G2 phase? | Preparation for mitosis. |
| 6. What happens during the M phase? | Mitosis anad cytokinesis. |
| 7. What happens during interphase? | The cell grows and replicates its DNA and centrioles. |
| 8. What happends during prophase? | The chromatin condenses into chromosomes. The centrioles separate, and a spindle gegins to form. The nuclear envolope breaks down. |
| 9. What happends during metaphase? | The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere. |
| 10. What happends during anaphase? | The sister chromatids separate into individual chromosomes and are moved apart. |
| 11. What happens during telophase? | The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelopes will form. |
| 12. What happens during cytokinesis? | The cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes |
| 13. Name two things that are in a plant cell and not an animal cell. | *Cell Plate*Cell Wall |
| 14. What is the "in-between" period of growth called? | Interphase |
| 15. What is the centromere? | It's located in the middle of the chromatides holding the origional and copy together. |
