• Contributions of Leeuwenhoek . Answer: Leeuwenhoek is known as the father of
microbiology for his pioneering work in microscopy and for being the first to
observe and describe single-celled organisms.
• Contributions of Jenner . Answer: Jenner developed the first successful smallpox
vaccine, which laid the foundation for immunology.
• Contributions of Koch . Answer: Koch established the germ theory of disease and
developed postulates to link specific pathogens to specific diseases.
• Contributions of Pasteur . Answer: Pasteur is known for his discoveries of the
principles of vaccination, microbial fermentation, and pasteurization.
• Classification in microbiology . Answer: Classification is the process of
organizing living organisms into groups based on shared characteristics, using a
hierarchical system of taxons.
• Major biological taxons . Answer: The major biological taxons include Domain,
Kingdom, Phylum, Class, Order, Family, Genus, and Species.
• Scientific naming rules . Answer: The scientific name of an organism is written in
italics, with the genus name capitalized and the species name in lowercase.
, • Pathogens and disease symptoms . Answer: Pathogens are microorganisms that
can cause disease, and each pathogen is associated with specific signs and
symptoms.
• Major shapes of bacteria . Answer: The major shapes of bacteria include cocci
(spherical), bacilli (rod-shaped), and spirilla (spiral-shaped).
• Characteristics of viruses . Answer: Viruses are acellular entities that require a
host cell to replicate and are composed of genetic material surrounded by a protein
coat.
• Morphological differences between microbes . Answer: Bacteria are prokaryotic
and have a simple structure, while viruses are much smaller and lack cellular
structure, and fungi are eukaryotic with more complex structures.
• Bacteriophage structure . Answer: A bacteriophage consists of a head (capsid)
containing genetic material, a tail, and tail fibers used to attach to bacterial cells.
• Total magnification calculation . Answer: Total magnification is calculated by
multiplying the magnification of the ocular lens by the magnification of the
objective lens.
• Lens system modifications . Answer: Modifications in the lens system of a
compound microscope can affect the clarity, brightness, and resolution of the
image.
• Light vs. electron microscopy . Answer: Light microscopy uses visible light to
illuminate specimens, while electron microscopy uses electrons, allowing for much
higher resolution.
