Document Summary
Microorganism: derived from the greek: mikros, {small} and organismos, {organism} >microscopic organism which includes either a single cell (unicellular) or a group of identical cells (few that are composed of same cells = non differentiated) >viruses are studied by microbiologists, they are much smaller than bacteria. >whether viruses is an organism is still debatable. >microbiologists believe that viruses are not alive and an organism implies something that is alive thus viruses are not an organism. Animal cells, plant cells are alive as well as an ant. An ant is a macro organism (can be seen with visible eye) Organelles are within a small range of bacteria. >part of a cell so not a microorganism (not alive) >too small to be seen with naked eye. >multicellular organism, has many cell types so it is not a microorganism. >though liver cells are in a living human body they are not alive so not an organism and they also can"t live independently.
