Cell Reproduction
| Term | Definition |
|---|---|
| Asexual reproduction | Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent |
| Cell cycle | Series of events in which a cell grows, prepares for division, and divides to form two daughter cells |
| Mitosis | Part of eukaryotic cell division during which the cell nucleus divides |
| Prophase | First stage in mitosis where the chromosomes condense and the nuclear membrane brakes down |
| Metaphase | Second stage in mitosis where the chromosomes line up down the middle of the cell |
| Anaphase | Third phase in mitosis where the chromosomes move towards opposite poles (ends) of the cell |
| Telophase | Final phase in mitosis where the nucleus reforms and chromosomes relax |
| Cytokinesis | Division of cell after mitosis |
| Chromosome | Threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next |
| Cancer | Uncontrolled cell growth |
| Mutation | Change in the genetic material of a cell |
| Carcinogen | Substance capable of causing cancer |
| Tumor | Mass of rapidly dividing cells that can damage surrounding tissue |
| Apoptosis | The process of programmed cell death |
| Meiosis | Process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell; creates gametes |
| Independent assortment | Genes for different traits can segregate independently during the formation of gametes |
| Recombination | The exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent |
| Sexual reproduction | Type of reproduction in which cells from two parents unite to form the first cell of a new organism |
| Homologous chromosomes | Chromosomes of the same size with the same genes |
| Segregation | Separation of alleles during gamete formation |
| Crossing over | Process in which homologous chromosomes exchange portions of their chromatids during meiosis |
| Gamete | Sex cell |
| Fertilization | Process in sexual reproduction in which male and female reproductive cells join to form a new cell |
