7 Mitosis
7th grade biology Mitosis
| Question | Answer |
|---|---|
| List all the events of the cell cycle. | 1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase 6. Cytokinesis |
| List the 3 phases in the Interphase. | 1. G1-cell growth 2. S-DNA replication 3. G2-preparation for mitosis |
| What happens in the prophase? | Chromatin condenses into chromosomes and the nuclear membrane breaks down |
| What is mitosis? | The division of the nucleus in 4 phases |
| What happens in the metaphase? | Chromosomes line up across the center of the cell and each chromosome is connected to a spindle fiber |
| What happens in the anaphase? | Sister chromatids separate into individual chromosomes and are pulled apart |
| What happens in the telophase? | Chromosomes gather at opposite ends of the cell and 2 new nuclear membranes form around them |
| What happens in cytokineses? | The cytoplasm divides |
| In what cell does the "draw string effect" forms cleavage furrows (which pinches the cell into two parts) for cytokineses? | Animal cells |
| In what cell does a cell plate forms from inside out, and a cell wall begins to appear for cytokineses? | Plants cells |
| Each daughter cell has the same number of ___________ as the parent cell? | Chromosomes |
| What can happen if the growth of cells is not controlled? | Crowding and tissue damage can happen |

| C6H12O6 means what? | Glucose |
| 6O2 means what? | Oxygen |
| 6CO2 means what? | Carbon dioxide |
| 6H2O means what? | Water |
| ATP means what? | Energy |
| Proteins are made up of what? | Amino acids |
| Extra glucose in animals is stored in the liver as what? | Glycogen |
