Microorganisms: Friend and Foe

  • Microorganisms: Microorganisms are too small and are not visible to the unaided eye.
  • They can live in all kinds of environments, ranging from ice cold climates to hot springs and deserts to marshy lands.
  • Microorganisms are found in air, water and in the bodies of plants and animals.
  • They may be unicellular or multicellular.
  • Microorganisms include bacteria, fungi, protozoa and some algae. Viruses, though different from the above mentioned living organisms, are considered microbes.
  • Viruses are quite different from other microorganisms. They reproduce only inside the host organism; bacterium, plant or animal cell.
  • Some microorganisms are useful for commercial production of medicines and alcohol.
  • Some microorganisms decompose the organic waste and dead plants and animals into simple substances and clean up the environment.
  • Protozoans cause serious diseases like dysentery and malaria.
  • Some of the microorganisms grow on our food and cause food poisoning.
  • Some microorganisms reside in the root nodules of leguminous plants. They can fix nitrogen from air into soil and increase the soil fertility.
  • Some bacteria and blue green algae present in the soil fix nitrogen from the atmosphere and convert into nitrogenous compounds.
  • Certain bacteria convert compounds of nitrogen present in the soil into nitrogen gas which is released to the atmosphere.
  • Pathogens: Some of the microorganisms cause diseases in human beings, plants and animals. Such disease causing microorganisms are called pathogens.
