The discovery of cells would not have been possible without advancements in microscopes. Scientist Robert Hooke improved how microscopes worked in 1665. He made what is called a compound microscope. It used three lenses and light. It lit up and enlarged whatever you put under it.

Based on this paragraph, choose the statement that is TRUE.

• Robert Hooke was the only scientist to make his own microscope.

• Robert Hooke's creation of the microscope was the first time that scientists used lenses.

• Scientists needed to develop new technology to be able to see and identify cells.

• Scientists knew that cells existed before the microscope; they just hadn't seen one.
