Study Notes
Electron Microscopy and Microorganisms
- Electron microscopy uses electrons instead of light photons to image cells and cell structures
- Electrons provide "illumination" with a shorter wavelength than light photons and electromagnets function as lenses
- The resolving power of electron microscopy is 0.2 nm, while light microscopy is 0.2 µm
- Scanning electron microscopy is used to observe external features of cells, while transmission electron microscopy is used to observe internal cell structures
- Examples of bacterial cells observed using electron microscopy include E. Coli, Salmonella, and Staphylococcus
- No living specimen can survive under high vacuum and chemical fixatives used in electron microscopy
- Light microscopes enable the user to see living cells in action, and new strategies involving video cameras, polarized light, fluorescent dyes, and digitizing computers have led to vast improvements in contrast
- Microorganisms are categorized into prokaryotic microorganisms (bacteria, archaea), eukaryotic microorganisms (fungi, protozoa, algae), and non-cellular microorganisms (viruses, prions)
- Prokaryotic cells lack a nucleus, have a cell wall, and no cell organelles, while eukaryotic cells have a nucleus, some with a cell wall, and contain cell organelles
- Eukaryotic cells have nucleic acid in a nucleus bounded by a nuclear membrane, while prokaryotic cells have nucleic acid not bounded by a nuclear membrane and usually contain one circular chromosome composed of DNA associated with histone-like proteins
- Eukaryotic cells undergo cell division by mitosis and meiosis, while prokaryotic cells usually undergo binary fission and are haploid
- Eukaryotic cells have respiratory enzymes and electron transport chains located in the mitochondria, while in prokaryotic cells, they are located at the cytoplasmic membrane
