Meiosis
| Question | Answer |
|---|---|
| Meiosis | The type of cell division used to create gametes. Results in 4 genetically unique gametes at a time. |
| Mitosis | The type of cell division used to create somatic cells. Results in 2 genetically identical somatic cells at a time. |
| Cell division | When cells divide to create more cells. |
| Somatic | Cells in the body. These cells are not used for reproduction, and are diploid. |
| Gamete | Cells used to combine DNA during sexual reproduction. These cells are haploid. |
| Fertilization | The combination of 2 haploid gametes. |
| Zygote | The diploid cell resulting from fertilization. |
| Diploid | A cell with a full set of chromosomes. |
| Haploid | A cell with a half set of chromosomes. |
| 23 | The number of chromosomes in a human gamete. |
| 46 | The number of chromosomes in a human somatic cell. |
| n | An abbreviation for haploid. |
| 2n | An abbreviation for diploid. |
| Sexual reproduction | Reproduction involving the combination of DNA from 2 parent organisms. |
| Asexual reproduction | Reproduction where 1 parent makes genetically identical offspring. |
| Parent cell | A cell before it divides. |
| Daughter cell | A cell resulting from cell division. |
| Interphase | The part of a cell's life span where it grows, carries out cell activities, and duplicates its DNA before it begins dividing. |
| Ovum/Egg | The female gamete in animals. |
| Sperm | The male gamete in animals. |
| Polar Body | Unused cells resulting in meiosis in females. These cells are incapable of being fertilized. |
