Cells
Structure and Function of Organelles
| Function | Organelle |
|---|---|
| Barrier that encloses a cell | Cell membrane |
| Regulates passage of materials in and out of a cell | cell membrane |
| structural organelle that consists of proteins and a phospholipid bilayer. | cell membrane |
| The term "fluid mosaic model" refers to the: | cell membrane |
| Controls the cell's activities | nucleus |
| Storage site of DNA and genetic info | Nucleus |
| Site where RNA is copied from DNA to direct protein synthesis | Nucleus |
| Site of protein synthesis | Ribosome |
| Translates mRNA and builds proteins | Ribosome |
| Found in loose cytoplasm or attached to parts of the ER | Ribosome |
| This part of the cell contains various organelles | cytoplasm |
| Made of a gelatin-like, watery fluid that contains salts, minerals, and many organic molecules and compounds. | cytoplasm |
| Rigid cell structure used for support in plants' cells, algae cells, fungi, and many other prokaryotes. | Cell wall |
| found outside the cell membrane in plants; much thicker than a cell membrane | Cell wall |
| Made of cellulose in plant cells | Cell wall |
| Storage area found in both plant and animal cells | vacuole |
| stores food, water, and metabolic wastes of cells | vacuole |
| Known as the "powerhouse" of the cell | mitochondria |
| site of cellular respiration | mitochondria |
| transfers energy stored in organic compounds (like glucose) to molecules of ATP | mitochondria |
| Intracelluar highway where molecules can move from one part of the cell to another | ER |
| Has two types: rough and smooth | ER |
| May or may not have attached ribosomes | ER |
| receives proteins from ribosomes to prepare proteins for export | ER |
| contains chlorophyll | Chloroplast |
| converts sunlight into chemical energy contained in molecules of glucose | Chloroplast |
| site of photosynthesis | Chloroplast |
| Processes and packages substances for export from the cell | Golgi |
| Works with ER to prepare materials for release from the cell. | Golgi |
| Completes final modifications of proteins | golgi |
| ships proteins off | golgi |
| can digest old organelles and foreign substances such as viruses and bacteria | lysosomes |
| functions in "programmed cell death" to rid an organism of damaged or dead cells | lysosomes |
| These organelles may be produced by budding from the trans face of the golgi | lysosomes |
| A network of protein fibers extending throughout the cytoplasm | Cytoskeleton |
| helps move materials around the inside of the cell | Cytoskeleton |
| provides mechanical support for cell and helps maintain its shape | Cytoskeleton |
