| Term | Definition |
|---|---|
| DNA | molecule that contains information that determines the traits that a living thing inherits |
| Chromosomes | a threadlike structure |
| Cell Cycle | the life cycle of a eukaryotic cell |
| Interphase | the part of the cell cycle during which the cell is not dividing |
| Mitosis | the part of the cell cycle during which the nucleus divides |
| Cytokinesis | the division of the parent cell's cytoplasm |
| Homologous Chromosomes | carry the same genes |
| Meiosis | the type of cell division that produces haploid sex cells such as eggs and sperm cells |
| Asexual Reproduction | one organism produces one or more new organisms that are identical to itself |
| Sexual Reproduction | two parents each contribute a sex cell to the new organism |
| Fertilization | when a sperm cell and egg join together |
| Binary Fission | the form of asexual reproduction in prokaryotes; the parent organism splits in two producing new cells that are exactly like the parent cell |
| Budding | an organism develops tiny buds on its body and grows until it forms a new full-size organism that is genetically identical to the parent |
| Spores | a specialized cell that can survive harsh conditions and is produced asexually by one parant |
| Vegetative Reproduction | mitosis makes vegetative reproduction possible |
| Prophase | the chromosomes in the nucleus of a cell condensed and are held together by a centromere, the membrane around the nucleus breaks down |
| Metaphase | chromosomes line up in the middle of the cell centromeres of the chromosomes are the same distance from each side of the cell |
| Anaphase | the chromatids separate to opposite sides of the cell and end up with a complete set of chromosomes |
| Telophase | the cell now has two identical nuclei that and the chromosomes become less condensed and Cytokinesis begins |
| Meiosis I | pairs of homologous chromosomes and sex chromosomes split apart into two new cells |
| Meiosis II | results in four haploid sex cells; male organisms these cells develop into sperm cells and in female orgasms these cells become eggs. |
