Cellular Reproduction Unit Vocab-Chapter 10
| Question | Answer |
|---|---|
| Cell Cycle | a series of events that take place from one cells divison to the next |
| interphase | a period of growth and development in eykaryotic cells |
| Mitosis | the process in which the neucleus divides to form two identical neucli |
| chromosomes | a structure in the neucleus that contains hereditary material |
| prophase | Chromatids are visible and the neuclear membraane disentigrates. The centroles move to opposite ends of the cell and spindle fibers are streaching over the cell. |
| Metaphase | The pairs of chromatids line up across the center of the cell |
| anaphase | cell centrome divides and spindle fibers shorten & move to opposite ends ofthe cell. |
| Telophase | The process when the spindle fibers start to dissappear, the chromosomes start to uncoil, and a new neucleus forms. |
| Cytokinesis | Divison of the cytoplasm |
| Sexual Reproduction | A type of reproduction in which 2 sex cells usually a sperm & egg join to form a zygtote, which will form a new organism |
| Asexual reproduction | A type of reproduction in which a new organism is formed. |
| Sperm | Male Sex Cell |
| Egg | Female Sex Cell |
| fertilization | The joining of an egg and sperm |
| Zygtote | The cell that forms after fertilization |
| Diploid | When cells have pairs of similar chromosomes |
| hapliod | When cells don't have pairs of chromosomes ( Sex cells) |
| Meiosis | Cell Divison that produces haploid sex cells |
| DNA | Deoxyribonucleic acid. Contains genetic material for an organism's growth and function |
| gene | A section of DNA on a chromosome |
| RNA | Goes to neucleus and gets code from DNA& takes code back to ribmosomes in the cytoplasm |
| Mutations | A permanent change in the DNA sequence of a gene or chromosome of a cell |
