Bio Terms 8.2
| Term | Definition |
|---|---|
| Binary Fission | -A form of asexual reproduction in a single-celled organisms by which one cell divides into two cells of the same size. |
| Mitosis | -In eukaryotic cells, a process of cell division that forms two new nuclei. each of which has the same number of chromosomes. |
| Asexual Reproduction | -Reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent. |
| Meiosis | -A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells. |
| Gamete | -A haploid reproductive cell that unities with another haploid reproductive cell to form a zygote. |
| Interphase | -A period between two mitotic or mitotic divisions during which the cell grows, copies DNA, and synthesizes proteins. |
| Cytokinesis | -The division of the cytoplasma of a cell; cytokinesis follows the division of the cell's nucleus by mitosis or meiosis. |
| Prophase | -The first stage of mitosis and meiosis in cell division; characterized by the condensation of the chromosomes and the dissolution of the nuclear envelope. |
| Spindle Fiber | -One of the microtubules that extend across a dividing eukaryotic cell; assists in the movement of chromosomes. |
| Metaphase | -One of the stages of mitosis and meiosis, during which all of the chromosomes move to the cell's equator. |
| Anaphase | -A phase of mitosis and meiosis in which the chromosomes separate. |
| Telophase | -The final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes. |
| Cell Plate | -The precursor of a new plant cell wall that forms during cell division and divides a cell into two. |
