Cell Division
Term | Definition |
---|---|
Binary Fission | Division of a prokaryotic cell into two offspring cells |
Mitosis | Results in the new cells with genetic material identical to the original cell's genetic material |
Asexual Reproduction | Production of offspring from one parent |
Melosis | Occurs during the formation of gametes; it reduces the number of chromosomes number by half in new cells |
Gametes | Haploid reproductive cells |
Interphase | The time between cell division |
Cytokinesis | Division of the cell's cytoplasm |
Prophase | The first phase of Mitosis; begins with the shortening and tight coiling of DNA into rod-shaped chromosomes |
Spindle Fibers | Made of microtubules radiate from the centrosomes in preparation for metaphase |
Metaphase | The second phase of mitosis, karyotypes are often made from the phototmicrographs of chromosomes |
Anaphase | The chromatids of each chromosome separate at the centromere and slowly move, centromere first, toward opposite poles of the dividing cell |
Telophase | After the chromosomes reach opposite ends of the cell, the spindle fibers disassemble, and the chromosomes return to a less tightly coiled chromatin state |
Cell Plate | Vesicles from the Golgi Apparatus join together at the midline of the dividing cell to form a cell plate |
