Yonkies but Goodies Department: everything a needs to know about the contents of a plant cell . . . drawn by Gdau.I [9½], which arrived for my birthday. I hope it was some recycled school work rather than created specially for me. In any case it's well above the median for what I grew to expect when this drawing was turned in by 1st Year Biology students [19½] at The Institute.
The annoying thing with the voting age students is that pictures like this were routinely turned in as part of a report about microscopy. With a standard optical microscope, even if the material is stained as well as could be expect, you just can't see that much detail. Mitochondria are about the size of a bacterium like Escherichia coli - 1.5μm - that is just resolvable with the 100x objective lens. But only if you use a drop of oil which exactly the same refractive index as glass to connect the lens with the slide. Without this "immersion oil", the distortion as the light bends at the glass-air-glass transitions fuzzes everything up. It's the same as when a bamboo appears to bend when you put it into water. It's something that spear-fishers have to compensate for if they are going to bring home the bacon.to discover lysosomes.
