BiologyCells, tissues and organsGCSEAQA Created by: [email protected]Created on: 28-10-17 13:35 Pros of Light Microscopes Relatively cheap, can be used almost anywhere, they can magnify live specimens 1 of 15 Cons of Light Microscopes Must use stains for certain things, less detail 2 of 15 Pros of Electron Microscopes More detail seen, can produce 3D images 3 of 15 Cons of Electron Microscope Large, very expensive, have to be in special conditions - special temp, pressure and conditions, the cells must be dead, difficult to prepare slides. 4 of 15 1 km is equal to... 100m 5 of 15 1m is equal to 100cm 6 of 15 1cm is equal to 100mm 7 of 15 1mm is equal to 1000μm 8 of 15 1μm is equal to 1000nm 9 of 15 What is resolution? The ability to distinguish between two points 10 of 15 What does the resolving power on a microscope determine? The level of detail shown 11 of 15 What is magnification? It causes an object to appear bigger 12 of 15 Resolving power of a Light microscope Little detail seen, can magnify up to x2000 and up to 200μm 13 of 15 Resolving power of a Scanning Electron Microscope Good detail, 3D image seen, can magnify up to x500,000 and up to 10nm 14 of 15 Resolving power of a Transmission Electron Microscope Fine detail, 2D image seen, can magnify up to x1,000,000 and up to 0.2nm 15 of 15
