Combined Science Biology B1 - Microscopy 0.0 / 5 ? ScienceCellsMicroscopesGCSEAll boards Created by: liv_hollieCreated on: 25-03-18 22:10 What do microscopes do? Let us see things that we can't see with the naked eye 1 of 9 Light microscopes Use light and lenses to form an image of a specimen and magnify it 2 of 9 What can you see through a light microscope? Individual cells and large subcellular structures e.g nuclei 3 of 9 Electron microscopes Use electrons instead of light to form an image 4 of 9 What are the features of an electron microscope compared to a light microscope? Higher magnification and resolution (sharper image) 5 of 9 What can you see through an electron microscope? Much smaller things in detail e.g internal structures of mitochondria and chloroplasts. They let us see tinier things e.g ribosomes and plasmids 6 of 9 FORMULA FOR MAGNIFICATION Magnification = image size / real size 7 of 9 Image size = Magnification x real size 8 of 9 Real size = Image size / magnification 9 of 9
