Cell Mesurement

• Organisms are made up of cells.
• The type of microscope used in a school laboratory is a compound microscope.
• The human eye can see objects as small as around 0.05 mm.
• In microscopy, a whole organism, cells, tissues, a small piece of tissue, or other structures, such as hair, pollen grains, are viewed with a microscope so that it appears larger.
• A compound microscope uses two lenses, the objective lens and the eyepiece.
• A microscope is required to see cells in any detail.
• The very short focal length objective lens produces a greatly-magnified image, then the short focal length eyepiece magnifies this further.
