| cell division | the division of a cell into two daughter cells with the same genetic material. |
| cell cycle | the cycle of growth and asexual reproduction of a cell, consisting of interphase followed in actively dividing cells by prophase, metaphase, anaphase, and telophase |
| interphase | chromosomes are copied, ccopies appear as chromatin, nucleolus and nuclear envelope are visible (nucleolus make ribosomes |
| prophase | chromosomes become visible, centrioles appear and move to opposite ends of cell, spindle fibers form and nuclear membrane disappears |
| metaphase | chromosomes line up across center of cell, spindle fibers attach to centromeres |
| anaphase | sister chromatids are pulled apart |
| telophase | chromosomes lose shape and appear as chromatin, nuclear membranes reform |
| cytokinesis | cytoplasm pinches in half |
| cancer | uncontrolled cell growth |
| tumor | mass of cells formed from cancer |
| nucleolus | a small dense spherical structure in the nucleus of a cell during interphase. |
| chromatin | the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA. |
| nuclear envelope | The double-layered membrane enclosing the nucleus of a eukaryotic cell. The nuclear envelope has pores that allow the passage of materials into and out of the nucleus |
| centrioles | a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. |
