Document Summary
In library on first floor at reserve desk: Microbiology: an evolving science 1st edition- call number is rx52. Size of prokaryotes: prokaryotes are generally, small size allows, prokaryotic cells can be as small as 0. 2 m. The smallest eukaryotic cells are 2 m: ______________________- typically have diameter of 2 m, some microbiologists have proposed that bacteria smaller than 0. 2 m exist in nature, cells referred to as. Microscopy: simple microscopes, one lens, magnify 50 300x, compound microscopes, multiple lenses, much higher magnification, ones in 2051 lab magnify 1000x. Lens system of compound microscopes: condenser lens located between light source and specimen, focuses light rays up through specimen, objective lens system, closest to specimen, typical scope has 10, 40, & 100x objective lenses. In each objective are multiple lens: ocular lens system, closest to the eye, typically magnify 10x, each ocular has multiple lenses. Resolution: ability to distinguish between 2 objects that are close together.
