When you look at some objects, you discover that they are made up of individual parts, such as the pieces in puzzles or the segments in plastic toys. 
However, other objects need a closer look with a magnifying glass or microscope to see their small parts. For example, when you look through a hand lens at a computer picture, you will see that it is made up of thousands of tiny squares of color, called pixels. What are the smallest units in living things?

The cell is the basic unit of life. Cells are the smallest unit in living things, but most cells are too small to be seen with the naked eye. So, what evidence do we have that living things are made of cells, if cells cannot be seen? Prior to the invention of the microscope, the existence of cells was unknown. 

A microscope is a scientific tool that uses a combination of lenses to make a small object appear bigger than it is. In 1665, English scientist Robert Hooke looked through an early microscope that magnified the image of thin slices of cork to 30 times its original size. He saw many small compartments and coined the structures cells. Hooke was actually observing the cell walls of cork tissue taken from the bark of an oak tree.
