mitosis and meiosis
| Question | Answer |
|---|---|
| Meiosis | Cell division that Starts with diploid, Splits it into 4 haploid cells and Each cell has half the number of chromosomes. this is how your body makes the sperm or egg cells |
| How many cells will you end up in mitosis? | Twice as many as you started |
| How many chromosomes per cell will you end up with in mitosis? | The same number as you started. |
| What phase does mitosis start with? | Prophase |
| The most important part of this phase is that the chromatin is becoming a chromosome. (The genetic material is doubling) | Interphase |
| 90% of the time a cell is in this phase: | Interphase |
| In this phase the chromosomes line up in the middle of the cell. | Metaphase |
| In this phase the nuclear membrane and the nucleolus disappear. | Prophase |
| In this phase the nuclear membrane reappears and the nucleolus reappears. | telophase |
| In this phase the centrioles move to opposite sides of the cell | Prophase |
| In this phase the chromatids are being pulled to the opposite sides of the cell and the cell is getting bigger. | Anaphase |
| What is the correct order of phases in the cell cycle? | Interphase Prophase metaphase anaphase telophase cytokinesis |
| What is a haploid | A cell with one set of chromosomes (half the usual number) based of the human sperm and egg cells (gametes) |
| What is a diploid | A cell with two sets of chromosomes (Double -two sets) |
| How many cells are produced in meiosis | 4 |
