| one cell | unicellular |
| more than one cell | multi-cellular |
| cells become specialized during development (multi-celled organism) | differentiation |
| all living things use ______ | energy |
| the sum of all chemical reactions in a cell | metabolism |
| take in food to get energy | heterotroph |
| use source of energy to produce "food" | autotroph |
| green plants are autotrops that use ______ | photosynthesis |
| the capture by which they capture the suns energy & cange it into a useable form | photosynthesis |
| all organisms _______ to produce offspring | reproduce |

| an instrument that produces an enlarged image of an object | microscopes |
| increase in the size of an object | magnification |
| used to show detail clearly | resolution |
| used a light toproduce an enlarged view of an object | light microscope |
| developed first simple light microscope, had one lense | anton van leewanhook |
| used one lense to produce an enlarged image | simple light microscope |
| used 2 lenses to produce an enlarged image | compound light microscope |
| located in objective, positioned above the object | objective lens |
| located in the eyepiece | ocular lens |
| used to make object clear | fine focus |
