Study Notes
Microscopy and Cell Structures
- Electron Microscopy uses electrons instead of light photons to image cells and cell structures
- Electrons provide "illumination" with a shorter wavelength than light photons
- Electron Microscope uses electromagnets as lenses and functions in a vacuum
- Electron Microscopy involves speeding up electrons in a vacuum until their wavelength is extremely short
- Most electron microscopes can magnify objects up to 1 million times
- Scanning electron microscopy is used to observe external features of cells, while transmission electron microscopy is used to observe internal cell structures
- Light microscopes enable the user to see living cells in action
- New strategies involving video cameras, polarized light, fluorescent dyes, and digitizing computers have improved contrast in light microscopy
- Prokaryotic microorganisms include Bacteria and Archaea, while Eukaryotic microorganisms include Fungi, Protozoa, and Algae
- Eukaryotic cells have a nucleus, cell organelles, and nucleic acid bounded by a nuclear membrane, while prokaryotic cells do not have a nucleus, have a cell wall, and nucleic acid not bounded by a nuclear membrane
- Eukaryotic cell division occurs by mitosis and meiosis, while prokaryotic cell division occurs by binary fission
- Eukaryotic cells have a fluid phospholipid bilayer containing sterols in the cytoplasmic membrane, while prokaryotic cells also have a fluid phospholipid bilayer in the cytoplasmic membrane
