Characteristic Of Microorganisms

Microorganisms are living things.  Thus, they undergo life processes such as breath, grow and move. The life processes they undergo are similar to plants and animals but in a manner.


The sizes of protozoa range from microscopic to several millimeters. Most protozoa are found mainly in ponds, lakes and rivers. Some of them eat other microorganisms as food.


Fungi look similar to plants, but they do not have chroloplast. Therefore, they cannot synthesize their own food. There are variesties of sizes of fungi.


Bacteria are a one celled organism. They are named according to their shapes. Bacteria can form spores when they are in unfavourable conditions. These spores can withstand heat and dry conditions. Thus they can persist for a long time.


Viruses are unique in the sense that they can only be considered as living when they have entered living things. When they are not in the living things body they are in a crystalline form.
