| spindle | framework of centrosomes that acts as a guide for chromasomes during mitosis |
| centrosome | region of cytoplasmic material that in animal cells contain structures called centrioles. |
| prophase | the first stage in mitosis. The nuclear envelope breaks up and sister chromatids attach to the centromere. |
| metaphase | the phase in which the chromosomes are lined up in a plane in the middle of the cell and the spindle is fully formed |
| anaphase | the phase in which the daughter chromasomes are pulled to each pole. |
| telophase | the stage in which the nuclear envelop reappears around each daughter chromosomes and the cell divides |
| cell plate | plate of cell wall that forms inside a plant cell as it divides. |
| asexual reproduction | process in which offspring inherit all genetic material from one parent |
| sexual reproduction | process in which genetic material from two parents combines and produces offspring that differ genetically from either parent |
| chromatin | combination of DNA and protein molecules, in the form of long, thin fibers, making up the genetic material in the nucleus |
| chromosome | condensed threads of genetic material formed from chromatin as a cell prepares to divide |
| sister chromatid | one of a pair of identical chromosomes created before a cell divides |
| centromere | region where two sister chromatids are joined tightly together |
| cell cycle | sequence of events from the production of a eukaryotic cell to the time the cell itself reproduces |
| interphase | stage of the cell cycle during which a cell carries out its metabolic processes and performs its functions in the body |
| mitotic phase | stage of the cell cycle when a cell is actively dividing |
| mitosis | process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed, forming two daughter nuclei |
| cytokinesis | process by which the cytoplasm of a cell is divided in two; usually follows mitosis and meiosis |
