| Term | Definition |
|---|---|
| Cell division | Cell division is the process by which a parent cell divides into two or more daughter cells. |
| asexual reproduction | Asexual reproduction involves a single parent. It results in offspring that are genetically identical to each other and to the parent. |
| Asexual reproduction | Asexual reproduction involves a single parent. It results in offspring that are genetically identical to each other and to the parent. |
| chroromsome | A structure found inside the nucleus of a cell. |
| cell cycle | cell cycle is a series of events that takes place in a cell as it grows and divides. |
| mitosis | Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. |
| prophase | the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears |
| centromere | chromosomes first replicate so that each daughter cell receives a complete set of chromosomes. |
| metaphsase | the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers. |
| telophase | the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed. |
| chromatin | the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA. |
| interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. |
| cytokinesis | The division of the cytoplasm and the plasma membrane following the division of the nucleus resulting into two cells, each having its own . |
| chromatid | A chromatid is one of two identical halves of a replicated chromosome. |
| centriole | a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. |
| anaphase | . the stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cell. |
