| What is the Basic unit of living organisms? | Cells |
| What Microscope did Anton Va Leeuwenhoek use? | the light microscope |
| What did the light microscope contain? | it contained one lens and used to view objects |
| What does a compound light microscope contain? | it contains -two lenses -needs a light source -specimen may be alve or dead -up to 1,500 x larger |
| What microscope did Robert Hooke use? | he used the compound light microscope |
| What are the three main points of the cell theory? | -all organisms are composed of one or more cells -the cell is the basic unit of structure and organization of organisms -all cells come from preexisting cell |
