A | B |
Mitosis | When the nucleus of a cell divides to form 2 nuclei. |
Cytokinesis | When the cytoplasm of a cell divides into 2 parts. |
Asexual Reproduction | A type of reproduction that involves one parent making 2 identical offspring. |
Sexual Reproduction | A type of reproduction involving 2 parents making genetically unique offspring. |
DNA | Hereditary material |
Chromatin | This form of DNA is thin, twisted strands found in nondividing cells. |
Chromosomes | The form of DNA in which the long thin strands shorten and thicken into rodlike structures, found in replicating cells. |
Interphase | The phase of a resting cell, that is in between cell divisions. |
Centrioles | Two, tiny, cylindrical bodies that lie at right angles to each other in animal cells that direct chromosome movement during mitosis. |
Prophase | The first phase in mitosis, in which chromosomes become visible and centrioles move towards the poles. |
Chromatid | Each strand in a doubled chromosome. |
Centromere | A region connecting the chromatids. |
Spindle | Microtubules that extend from pole to pole in a cell and in which centromere become attached. |
Aster | Star-shaped microtubules extending from the centrioles. |
Metaphase | The second phase of mitosis in which centromeres line up at the equator and the centromeres divide to form two. |
Anaphase | The third phase of mitosis in which duplicate chromosomes move to opposite poles. |
Telophase | The 4th phase of mitosis in which the chromosomes uncoil at the poles and new nuclear membranes form. |
Cell Plate | A structure that forms in plant cells during telephase to seperate the rigid cell wall. |
