Study Notes
Microscopy and Microorganism Structures
- Electron Microscopy uses electrons and electromagnets to image cells at a resolving power of 0.2 nm, magnifying objects up to 1 million times.
- There are two types of Electron Microscopy: Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM).
- Light microscopes allow observation of living cells, using strategies like video cameras and fluorescent dyes for enhanced contrast.
- Microorganisms are classified into Prokaryotic (Bacteria, Archaea), Eukaryotic (Fungi, Protozoa, Algae), and Non-cellular (Viruses, Prions).
- Prokaryotic cells lack a nucleus, have a cell wall, and lack cell organelles, while Eukaryotic cells have a nucleus, some have a cell wall, and possess cell organelles.
- Eukaryotic and Prokaryotic cells differ in nucleic acid structure, cell division, cytoplasmic membrane composition, and presence of cytoplasmic structures.
- Eukaryotic cells have respiratory enzymes in mitochondria, while Prokaryotic cells have them at the cytoplasmic membrane.
- Eukaryotic and Prokaryotic cells have different cell wall compositions, with Eukaryotic cells having plant cells, algae, and fungi with cell walls, and Prokaryotic cells having Bacteria and Archaea with cell walls.
- Eukaryotic cells may have flagella or cilia for locomotion, while some Prokaryotic cells have flagella.
- Tortora, Funke, and Case's "Microbiology: An Introduction" covers the observation of microorganisms through a microscope and the functional anatomy of prokaryotic and eukaryotic cells.
