| cells | the basic units of life |
| organelles | all the different types of tiny organs inside of cells |
| cell theory | all cells come from pre-existing cells; cels are basic unit of structure; all organisms are made of cells |
| diffusion | movement from high to low |
| cell wall and chloraplasts | plant cells differ from animal cells because they have |
| ribosomes | protein is made in the ? |
| nucleus | the control center or brain of the cell |
| cell membrane | this is around the outside of the cell and controls what enters or leaves the cell |
| smooth er | transportation system that lack ribosomes |
| golgi bodies | used to package and store excess food for the cell |
| lysosomes | digestion occurs here |
| mitochondria | the "power house" of the cell |
| vacuoles | stores materials and water, plants have a large one |
| rough er | ribosomes are found on this transportation system |
| cytoplasm | the fluid material in the cell |
| isotonic | when water entering a cell equals the water that leaves the cell |
| hypertonic | when water leaves the cell and the cell shrinks |
| hypotonic | when more water enters the cell than leaves and the cell swells up |
| flagella | a structure used for locomotion (moving) |
| passive transport | diffusion is a form of this, it means moving from high to low |
| active transport | movement from low to high, needs ATP (energy) |
