reset
are minute living things that individually are TOO SMALL TO BE SEEN BY THE NAKED EYE. The group includes bacteria, fungi (yeasts and molds), protozoa and microscopic algae. It also includes viruses which are microscopic but are regarded as non-cellular entities.
MICROORGANISM
are UNICELLULAR (single-celled) organisms. Because they have no nucleus, the cells are described as PROKARYOTIC.
