PPT-The microscope The microscope led to the discovery of cells.

They were discovered by Robert Hooke Most cells are microscopic too small to see without the aid of a microscope A microscope is an instrument that makes an object appear bigger than it is It took the invention of this relatively simple tool to lead to the discovery of cells. Microscopes are delicate and expensive instruments they should be handled with utmost care Before you use the microscope your instructor will explain its proper use Following are rule s that will protect the microscope and insure that you can make m The Big Questions.
