Oct 31, 2016 · It defines microbiology as the study of microorganisms too small to be seen with the naked eye. It discusses that microorganisms are found everywhere and play important roles in processes like photosynthesis, biodegradation, and vitamin production.
Feb 21, 2011 · The document provides an overview of microbiology and microorganisms. It discusses that microorganisms are too small to be seen with the naked eye and includes bacteria, fungi, protozoa, algae, and viruses. It also outlines several fields of microbiology like bacteriology, mycology, and virology.
Microbe, or microorganisms are minute living things that individually are usually too small to be seen with the unaided eye. ‘Micro’ means small or minute and ‘Bios’ is a Greek word that means life. (Microbe = Micro+bios) Micro-organisms: They are small organisms and are either microscopic or submicroscopic creatures.

Little boxes – cells Cell theory – all living things are made up of cells Hooke’s microscope was capable of showing large cells, it lacked the resolution so he didn’t see the microbe
Meat exposed to flies became infested • they claimed that fresh air was needed spontaneous generation.
• Pasteur demonstrated that microorganisms are present in the air and can contaminate sterile solutions, but that air itself doesn’t create microbes.
Experimented with medium to grow bacteria Using agar (a gelatin-like product derived from seaweed) Add various nutrients necessary to grow certain organisms. He provided proof that a bacterium causes anthrax (Koch’s postulates)
