| membranous system, consisting of flattened sacs * vesicles; packages proteins for export | Golgi Apparatus |
| contorl center of the cell; necessary for cell division & cell life; contains DNA | nucleus |
| two rod-shaped bodies near the nucleus; "spin" the mitotic spindle in cell division | centrioles |
| dense darkly-stained nuclear body; possible packaging site for ribosomes | nucleolus |
| attached to membrane system involved in transport of proteins within the cell | endoplasmic reticulum |
| threadlike structures in the nucleus; contain DNA | chromatin or chromosomes |
| external boundary of cell; confines cell contents, regulates entry & exit of materials | cell membrane |
| contains digestive enzymes; "suicide sacs" of the cell | lysosomes |
| controls the release of energy from ATP; where cellular respiration occurs | mitochondria |
| process of scattering a substance evenly | diffusion |
| diffusion of water through a selectively permeable membrane | osmosis |
| sequence of DNA that determines a trait | gene |
| high energy molecule | ATP |
| solution of the same concentration as the cell's solution | isotonic |
| membrane protein; pumps against the diffusion gradient | permease |
| solutionof higher solute concentration than that of the cell | hypertonic |
| diffusion of solutes | dialysis |
| solution of lower solute concentration than that of the cell | hypotonic |
| cell division | mitosis |
| DNA duplication | replication |
| process of a cell engulfing a foreign material | endocytosis |
| process of a cell engulfing a solid substance | phagocytosis |
| process of a cell engulfing a liquid substance | pinocytosis |
| movement against a concentration gradient; may require a protein pump; ie. phagocytosis | active transport |
| movement with a concentration gradient; ie. diffusion | passive transport |
| passive transport helped by membrane molecules | facilitated diffusion |
