"The Living Cell"

I'd recommend turning this paper in first! Good Job!!!!! THE LIVING CELL         The cell is the smallest unit of living matter that can exist by itself. Some plants and animals consist of only a single cell. Others are composed of billions of cells.                  Cells exist in a variety of shapes and sizes. They may, for example, be cube- shaped or flat. Scientists who study cells have determined that a single cell may be as large …

…instruments use special equipment to reveal the refraction, or bending, of light passing through objects, enabling the viewer to see cell details not visible with other microscopes. The electron microscope uses waves of electrons, rather than light, and magnetic fields, rather than lenses, to get an image. With the aid of electron microscopes 200 times more powerful than the best light instruments, molecular biologists have learned a great deal more about the tiny structures within cells.
