Electron micrographs - the big picture

  • What are they? Imagine you've got a super-powered microscope that lets you see the tiniest parts of a cell. That's an electron microscope, and the pictures it takes are called electron micrographs.
  • Real-World Example: Think of it like Google Earth for cells. You can zoom in and see every tiny detail, just like looking at streets and houses from space.

Artefacts - the unwanted guests

  • Definition: Artefacts are like photobombers in a picture. They aren't supposed to be there, but they appear because of the way the specimen was prepared.
  • Real-World Example: Imagine baking a cake and accidentally leaving the spoon inside. That spoon is like an artefact in your cake!

Drawings - a clearer view

  • Why Draw? Sometimes drawings can show cell structures more clearly than the actual electron micrographs.
  • How to Draw? Think of it like drawing a cartoon version of a photo. You simplify the details but keep the important stuff.
  • Real-World Example: Think about drawing a map of your room. You may not draw every book on your shelf, but you'll include the bed, desk, and main pieces.
