Protists are single and multicellular organisms that are plant-like, animal-like and fungi-like. They evolved from bacteria and represent the intermediate step in the evolution of the other three kingdoms. There are 12 phyla in this kingdom, most of which live in water.
Historically, protozoa were defined as single-celled organisms with animal-like behaviors, such as motility and predation. The group was regarded as the zoological counterpart to the  protophyta , which were considered to be plant-like, as they are capable of photosynthesis.oldfuss erected Protozoa as a class containing what he believed to be the simplest animals.
