This wasn't something I was anticipating as an issue, but I'm finding it fairly difficult to determine which organelle has been shown. Perhaps I've become too reliant on the cartoon drawings, because I have no problems with them. Any advice to address this matter? :)
-
Have a look at a labelled electromicrograph and try to remember what the organelles look like. That's really the only way. The organelles do sort of look like their cartoon representations though :P

The best way of remembering electron microscopic images of cell structures and organelles is to jump on the net, print off every organelle/structure in about 3 different forms and remember a few characteristics of each organelle. For example, determining a Mitochondrion will be made easy if you note the cristae (compartments) in the surface of the outer membrane, and apply your knowledge of their characteristics and apply it to the diagram. Just devise a list and you'll be good to go Stick :)
Ooh, and also practice drawing cell organelles and structures (mostly your plasma membrane), because its good practice to reconsolidate your knowledge of their appearance and ultimately their functions also.

They won't make the micrograph purposely hard or anything, they'll make sure they get the right angle so the picture isn't taken through the sliced *middle* of an organelle either. The golgi will be long, curved strips for example.

Thanks for the advice everyone. I'll search up some images now and stick them in.

I struggle with the high definition colouring SEM images in the Nature of Biology textbook. Sometimes the structure can look a bit ambiguous.
