| Do Meiosis cells skip Interphase II? | Yes, The two cells produced by Meiosis I both enter a second round of Meiosis division at the same time but there is NO second round of Interphase where chromosomes are replicated again. Instead, they go straight into Prophase II. |

| Division | either mitosis or meiosis |
| Mitosis | division and asexual cloning of cells |
| Meiosis | division of cells in reproductive organs in order to create the sex cells needed for sexual reproduction |
| Somatic Diploid Cells (2N) | normal everyday body cells which have chromosomes in homologous pairs of two. (“Di” means two.) |
| Homologous | chromosomes from your mom and dad that carry similar genes and are the same size (Remember, “Hom” means same or similar) |
| 2N | the symbol for diploid cells, where “N” represents the number of chromosomes in a single set from one parent in a particular organism |
| Cells Divide to: | Stay small (cells will keep on growing without division ) which helps them meet their nutrient requirements. If they get too big they starve. |
| Cells Divide to 2: | Produce clones of themselves through asexual reproduction (not sexually) so organisms can grow, develop and replace old or damaged cells |
| Tumors | a buildup of cells as a result of multiple mutations causing cells to divide uncontrollably and not die when they should |
| Benign Tumor | non-cancerous, slow growing, doesn’t damage surrounding tissue, doesn’t spread, usually doesn’t come back, BUT can turn malignant |
| Malignant Tumor | cancerous, fast growing, damages surrounding tissue, spreads throughout the body, often comes back because it can be hard to treat all mutated cells after spreading |
| 1. Interphase | phase before division where the cell grows, develops and replicates all of its DNA chromosomes into identical twin “Sister Chromatids” so when the cell divides, each new cell doesn’t end up with half the required amount of DNA |
| 2. Prophase | Sister Chromatids become visible because
nucleus breaks down |
| 2. Metaphase | Sister Chromatids meet in the middle |
| 3. Anaphase | Sister Chromatids are moved apart by Spindle Fibers made by Centrosomes organelles |
| 4. Telephase | two new nuclei form around each cluster of chromosomes |
| Cytokinesis | cell’s cytoplasm pinches in half
forms 2 new identical twin “Daughter Cells” |
| Haploid Cells (N) | contain half the # of chromosomes as Diploid (2N) cells (chromosomes are not in pairs) |
| Cytokinesis II | Cytoplasms pinch in half to form four unique, diverse sex cells called gametes |
| Do Meiosis cells skip Interphase II? | Yes, The two cells produced by Meiosis I both enter a second round of Meiosis division at the same time but there is NO second round of Interphase where chromosomes are replicated again. Instead, they go straight into Prophase II. |
