Terms | Definitions |
|---|---|
 Cytokinesis | Division of the cytoplasm (with its populations of mitochondria, chloroplasts, etc) between the daughter cells (in both mitosis and meiosis) |
| Spindle | The nucleic acid sequence of the chromosome which is the last to replicate, which does not happen until the beginning of anaphase |
| Centromere | The nucleic acid sequence of a chromosome which is the last to replicate, which does not happen until the beginning of anaphase |
| Centriole | Organelles which are used to produce cilia and flagella |
| Meiosis | Cellular reproduction that results in 4 daughter cells that are all different from the parent cell and from each other |
| Crossing Over | the pairing up of homologous chromosomes in preparation for "swapping genes" |
| Zygote | A cell formed by the fusion of male and femal gametes |
| Haploid | cell that has only one of each homologous chromosome(and thus only 1 gene for each trait) |
| diploid | cell which has both of the homologous chromosomes ( and thus 2 genes for each trait). |
| Homologous (chromosomes) | In a diploid cell, the pair of chromosomes that have the same genes (code for the same traits) |
| Anaphase | Separated chromosomes are pulled to their respective poles of the spindle |
| Telophase | Prophase in reverse. The nuclear membrane reforms, and the nucleus becomes visible |
| The nucleolus reforms | The chromosomes lapse into chromatin form |
| Interphase | The "normal" nondividing state of a cell. visible nucleoli, chromatin, nucleus. Replication of DNA occurs. |
