the size of cells and calculating magnification

  • the size of cells and calculating magnification
    • a typical plant cell may be about 0.1mm in diameter and an animal cell 0.02mm in diameter
    • prokaryotic cells are smaller - often about 0.02mm long
    • to describe the size of cells and sub-cellular structures, scientists use units that have different prefixes
    • when a microscope is used to look at cells, scientists will often take photographs or produce drawings
    • these images are many times larger than the real cell or structure
    • the magnification is how many times larger the image is than the real object
      • magnification= size of image/ size of real object
