| Question | Answer |
|---|---|
| Binary Fission | the division of a prokaryotic cell into two offspring cells |
| Mitosis | results in new cells with genetic material that is identical to the genetic material of the original cell |
| 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 | reduces the chromosome number by half in nnew cells |
| gamete | happens in the liod reproductive cells |
| interphase | The time between cell division a, divided into two phases |
| spindle Fiber | one of the microtubules that extend across a dividing eukaryotic cell; assists in the movement of chromosomes |
| Metaphase | second phase in mitosis, chromosomes are easier to identify by using a mircoscope , thus karyotypes are typically made from photomicrographs of chromosomes in metaphase |
| Anaphase | a phase of mitosis and meiosis in which the chromosomes separate |
| Telophase | After the chromosomes reach oppsite ends of the cell, the spindle fibers diassemble, and the chromosomes return to a less tightly coiled chromatin state. |
| Cell Plate | the precursor of a new plant cell wall that forms during cell division and divides a cell into two |
| Cytokinesis | the dividion of cells cytoplasm |
| Prophase | first phase of mitosis, begins with the shortening and the tight coiling of DNA in to rod-shaped chromosomes that can be seen with a light mircoscope |
