Protists are the the simplist organisms on earth because they are unicellular. Scientists think that they were the first life forms on earth. They belong to the kingdom Protista. Some have animal and plant-like characteristics. This makes them hard to classify. They are usually found in fresh water ponds.
The protist that causes malaria is a protozoa. There are three groups of protozoa: Ciliates, Amoebae, and Flagellates. The malaria causing protist is called Plasmodium, the best known protozoa menace. It causes about 800,0000 deaths a year.
