            The organisms that can not be seen by naked eye are called micro-organisms or microbes. The study of these
            organisms is called microbiology and the person who studies microbiology is called microbiologist. Micro-organisms
            are classified into five distinct categories : bacteria, fungi, protozoa, algae and viruses. Microbes are omnipresent.


             Discussion



                              Jack   :  Microbe ! ! Why can't I                     Suzi   :   Jack ! grow up……
                                         see any??
