| cilia | Hairlike organelles that allow some cells to move |
| flagella | Long whip-like tail that allows some cells to move |
| vessicles | Small membrane sacs used to store and move materials |
| diffusion | Molecule movement from high concentration to low concentration |
| tonicity | Difference in solute concentration between the cell and surrounding solution |
| facilitated diffusion | Using protein carriers and no cell energy to move materials |
| osmosis | Diffusion of water through a selectively permeable membrane |
| isotonic solution | Solution with the same amount of dissolved substances as a cell |
| hypotonic solution | Solution with the less dissolved substances and more water than a cell |
| hypertonic solution | Solution with the more dissolved substances and less water than a cell |
| passive transport | Movement of materials across a cell membrane without using energy |
| active transport | Movement of materials across a cell membrane using energy |
| endocytosis | Process of moving material into a cell using a vesicle |
| pinocytosis | Process of moving liquid material into a cell using a vesicle |
| phagocytosis | Process of moving solid material into a cell using a vesicle |
| exocytosis | Process of moving material out of a cell using a vesicle |
| organelle | Structure inside of a cell that has a specific function |
| plasma membrane | Separates cell from surroundings and controls what enters and leaves the cell |
| cytoplasm | All material between the plasmal membrane and nuclear membrane |
| nucleus | Control center for cell activities |
| nuclear envelope | Membrane that separates the nucleus from the rest of the cell |
| nucleoplasm | Fluid material found inside the nucleus |
| nucleolus | Dense body inside nucleus that is made of DNA, RNA, and proteins. It makes ribosomes |
| chromatin | Long thin threads of DNA found in the nucleus |
| endoplasmic reticulum | Continuous network membrane channels that transport materials through the cytoplasm |
| rough ER | Endoplasmic reticulum covered ribosomes |
| smooth ER | Endoplasmic reticulum that has no ribosomes |
| ribosome | Sites of protein synthesis in the cell |
| golgi apparatus | Flattened sacs that process, package, and store products to be released in vessicles |
| lysosomes | Single membrane packages of strong digestive (hydrolytic) enzymes |
| mitochondria | Organelle that carries out cellular respiration |
| cytoskeleton | Protein tubes found within the cell that give it shape |
| prokaryote | Cell type that does NOT have a nucleus and NO membrane organelles |
