| Question | Answer |
|---|---|
| cytoplasm | mostly water; provides medium for organelles |
| nucleus | large organelle surrounded by a double membrane in the center of most cells;houses the chromosomes |
| ribosomes | protein maker; may be free in the cytoplasm or attached ot ER |
| endoplasmic reticulum | system of folded membranes that transports proteins to other parts of the cell; smooth (no ribosomes) or rough (ribosomes) |
| golgi apparatus | flattened stack of membranes or sacs; organizes, labels, and packages proteins for export; makes lysosomes |
| lysosomes | tiny circular bodies located within the cytoplasm; contains digestive enzymes |
| mitochondria | football shaped organelle with many folds; burns sugar to produce energy; "Powerhouse" of the celll |
| cytoskeleton | thin tubes and threads of protein; forms the framework of the cell |
| cell membrane | gives the cell its shape; controls all import and export of materials; made of phospholipids with protein channels that act like gates |
| rough | endoplasmic reticulum that contains ribosomes is called this |
| smooth | endoplasmic reticulum that does not contain ribosomes is called this |
