| Term | Definition |
| Anaphase | the stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle |
| Asexual Reproduction | reproduction without the fusion of gametes |
| Cancer | any malignant growth or tumor caused by abnormal and uncontrolled cell division |
| Cell Cycle | series of events that cells go through as they grow and divide |
| Centromere | a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape |
| Chromatid | one of two identical strands into which a chromosome splits during mitosis |
| Crossing Over | the interchange of sections between pairing homologous chromosomes during the prophase of meiosis |
| Cytokinesis | organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells |
| Diploid | (genetics) an organism or cell having two sets of chromosomes or twice the haploid number |
| Egg | animal reproductive body consisting of an ovum or embryo together with nutritive and protective envelopes |
| Haploid | (genetics) an organism or cell having only one complete set of chromosomes |
| Interphase | period of the cell cycle between cell divisions |
| Meiosis | (genetics) cell division that produces reproductive cells in sexually reproducing organisms |
| Metaphase | the second stage of mitosis |
| Mitosis | cell division in which the nucleus divides into nuclei containing the same number of chromosomes |
| Prophase | the first stage of mitosis |
| Sexual Reproduction | reproduction involving the union or fusion of a male and a female gamete |
| Sperm | the male reproductive cell |
| Spindle | (biology) tiny fibers that are seen in cell division |
| Telophase | the final stage of mitosis |
