| chromosome | short stringy structures which contain DNA |
| cell cysle | the sequence of growth and division of a cell |
| mitosis | the process by which two daughter cells are formed each containing a complete set of chromosomes |
| cytokinesis | the division of the cytoplasm following mitosis |
| interphase | the phase where chromosomes and all organelles are duplicated |
| prophase | the first phase of mitosis, chromosomes form and double |
| centromere | structure that hold sister chromatids together |
| centriole | cylindrical microtubules whose role is to separate sister chromatids |
| spindle | the cagelike structure made of thin microtubules that attaches to the centromere of chromatids |
| metaphase | the phase where the doubled chromosomes line up in the middle of the cell and become attached to the spindle fibers at their centromeres |
| anaphase | the third phase of mitosis when the sister chromatids separate from each other by shortening of the spindle fibers |
| telophase | the chromosomes reach opposite poles of the cell, nuclear envelope reappears |
| tissue | cells that work together to perform a specific function |
| organ | tissues that work together to perform a specific function within the organism |
| organ system | multiple organs that work together form an organ system |
| cancer | growth caused by uncontrolled cell division |
| gene | segment of DNA that controls production of a protein |
