Document Summary
Science discipline; studies everything about unicellular organisms (microorganisms): their structure, growth, lifestyle, and interaction with the environment. Microorganisms = oldest and simplest form of life. Smallest form of life but constitute largest mass of living material. Can live in places unsuitable to other organisms; which allows to study limits of life as we know it. Carry out major processes for biogeochemical cycles. Other life forms require microbes to survive. As the simplest organisms this knowledge leads to understanding the chemical and physical basis of life. Microorganisms association and cooperation with each other and with the world at large, soil, water, animals and plants. Antoni van leeuwenhoek (cloth merchant, from netherlands) - began making and using simple microscopes. Made glass lenses of his own to examine quality of cloth. Often made a new microscope for each specimen. When he died, microbiology stopped developing as a discipline because he didn"t show anyone else how to make a lens.
