What is the relationship between magnification and resolution in light microscopy?
What is the relationship between magnification and resolution in light microscopy?
- Magnification and resolution are directly proportional, increasing one will automatically increase the other
- Magnification and resolution are inversely proportional, increasing one will decrease the other
- Magnification and resolution are unrelated, changing one will not affect the other
- Magnification can be increased without limit, but resolution cannot be improved beyond a certain point (correct)
What is the role of disinfectants and antiseptics in microbiology?
What is the role of disinfectants and antiseptics in microbiology?
- To identify different types of microorganisms under a microscope
- To increase the resolution of light microscopes
- To eliminate or reduce the number of microorganisms on surfaces and in cultures (correct)
- To promote the growth of microorganisms in cultures
What is the limitation of light microscopy in distinguishing small objects?
What is the limitation of light microscopy in distinguishing small objects?
- It can only distinguish objects larger than the wavelength of light
- It cannot distinguish objects that are smaller than half the wavelength of light (correct)
- It can distinguish objects of any size with the appropriate magnification
- It is limited by the intensity of light used in the microscope

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.
