Term | Definition |
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; occurs in organisms undergoing growth, development, repair, or asexual reproduction |
Asexual Reproduction | the production of offspring from one parent |
Meiosis | occurs during the formation of gametes; reduces chromosome number by half in new cells |
Gamete | haploid reproductive cells |
Interphase | the time between cell divisions |
Cytokinesis | the 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 that can be seen with a light microscope |
Spindle Fiber | made of microtubules; radiates from the centrosomes in preparation for metaphase |
Metaphase | the second phase of mitosis; chromosomes are easier to identify by using a microscope than during other phases |
Anaphase | 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 this |
