taxonomist
Organisms are classified based on their various similarities, and also based upon their relationship to other organisms.
A complex structural organization is an essential characteristic of a living organism
=A Microbiologist studies microscopic organisms.=
Scientists most likely consider KNOWN characteristics of KNOWN and named organisms when first classifying an unknown organism. They look for similarities and differences between what is known versus unknown. Major differences exclude known categories; strong similarities include the new organism into a known category. This is how scientists continually build a "family tree" of every organism.

The scientist who designed a system of classifying organisms based on their physical and structural similarities is Carl Linnaeus. He developed the binomial nomenclature system, which assigns each organism a two-part scientific name (genus and species) for easy identification and categorization.
A scientist who studies classification is called a taxonomist. Taxonomists examine the relationships among different organisms and group them into categories based on similarities and differences.

the similarities and differences of the organisms
To provide a useful response, kindly specify the two microscopic organisms you are inquiring about so I can accurately outline their similarities and differences for you.
Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities
