Taxonomic Differentiation of Microbes

Definition of Microbiology

It is a branch of science that deals with the study of microscopic forms of life these micro-organisms are less than 1 mm in size.

Characteristics of Micro-organisms 

  • These micro-organisms are very small in size generally less than 1 mm.
  • They are not visible through our naked eyes.
  • These organisms are either unicellular or multicellular.
  • Prokaryotic or eukaryotic in nature.
  • They may be motile or non motile.
  • Micro-organisms are present everywhere in our surrounding like air, water,soil, dust and bodies of plants, animals and human beings.

Amoeba
Amoeba
  •  Protozoa are unicellular, eukaryotic in nature.
  •  They are parasitic or saprophytic.
  •  The size range of protozoa is generally 10 – 50 micrometer.
  •  These organisms generally exist in aqueous environment and soil.
  •  They show motility by flagella, cilia, or pseudopodia.
  • Protozoa can absorbs their food material by cell membrane or by engulfing the food by phagocytosis.
  • Some parasites are pathogenic in nature .They can reproduce sexually or asexually.
