Which best describes the importance of the microscope to the development of cell theory? microscopes color different parts of cells so they can be seen with the naked eye. cells are too small to see with the naked eye, and a microscope magnifies them. the lenses in a microscope reduce the image of an organism to the size of a cell. microscopes trap “animalcules” from pond water so they can be studied.

Cells are too small to see with the naked eye. 

It's pretty straight forward, use the cross-out method. 

1) Microscopes MAGNIFY images, they don't color the cells. In fact, scientists have to use these chemicals to "stain" or color the cells to see them more easily through microscopes. 

2) If the lenses of a microscope reduced the image of an organism to the size of a cell, you'd be seeing a very tiny human through your microscope, instead of actual cells. 

3) Microscopes don't "trap" anything. In fact, scientists use plates or slides under microscopes to contain what they're studying.
