Magnifying Cells To see most cells, you need to use a microscope. A microscope has one or more lenses that enlarge the image of an object as though you.
“Cell Theory”. Leeuwenhoek made a simple microscope (mid 1600’s) magnified 270X Early microscope lenses made images larger but the image was not clear.
Microscopes. A microscope is… an instrument that produce images or pictures of small objects.
