Cell Division
Term | Definition |
---|---|
Binary Fisson | The division of a prokaryotic cell into two offspring cells. |
Mitosis | Results in new cells within genetic material that is identical to the genetic material of the original cell. |
Asexual Reproduction | The production of offspring from one parent. |
Meiosis | Occurs during the formation of gametes. |
Gametes | Haploid reproductive cells. |
Interphase | The time between cell divisions that is divided into three phases. |
Cytokinesis | The division of the cells cytoplasm. |
Prophase | The first stage of mitosis where chromosomes are a scatered across the cell with spindle fibers. |
Spindle Fibers | Micro tubules that attach to chromosomes and chromatids in mitosis. |
Metaphase | The second phase where the spindle fibers pull the chromosomes to the equator of the cell in a straight line. |
Anaphase | The third phase where the spindle fibers pull the chromosomes apart to opposite poles making chromatids. |
Telophase | The final phase where the spindle fibers finally pull the chromatids to opposite poles and the cell starts to separate. |
Cell Plate | The midline of the dividing cell in a plant cell. |
