| Active Transport | A process that requires an expenditure of energy to move a substance across a cell membrane |
| Centrosome | A cellular organelle that functions in the organization of the spindle during mitosis |
| Chromosome | A rodlike structure that appears in the nucleus of a cell during mitosis |
| Cytoplasm | The contents of cell surrounding its nucleus |
| Differentiation | The process by which cells become structurally and functionally specialized |

| Nucleolus | A small structure that occurs within the nucleus of a cell and contains RNA and proteins |
| Nucleus | A cellular organelle that is enclosed by a double-layered, porous membrane and contains DNA |
| Osmosis | The diffusion of water through a selectively permeable membrane |
| Permeanle | Open to passage or penetration |
| Phagocytosis | The process by which a cell engulfs and digests solid substances |
| Pinocytosis | The process by which a cell engulfs droplets of fluid from its surroundings |
| Ribosome | A cytoplasmic organelle that functions in the synthesis of proteins |
| Vesicle | A membranous sac within the cytoplasm that forms by an infolding of the cell membrane. |
