Terry and James are partners in a mystery lab. The boys have a compound light microscope and several unlabeled slides. Their task is to find out everything they can about the samples on the slides. Terry puts a slide on the microscope stage and focuses the lenses on the sample. He can see that the sample is made up of tiny cells.

Terry wishes he could magnify the cells even more so he could see more details. He suggests, “If we had an electron microscope, we could see all of the cells inside these cells, and even the cells inside those smaller cells!” James disagrees with Terry's thinking. What is wrong with Terry’s suggestion?

a)

It is not possible to see anything smaller than a cell with a microscope.

b)

Electron microscopes are not as powerful as compound light microscopes.

c)
