After thier discovery, the kingdom of Protista was then latter subdivided into subkingdoms. These include: Protozoa, Algae and Molds.

The protozoa subkingdom consists of these 7 phyla: Sarcomastigophora, Ciliophora, Apicomplexa, Microspora, Ascetospora, Myxozoa and Labyrinthomorpha

The protozoa are generally the bacteria consumers of the protista kingdom and they are heterotrophs.

This phylum is known for their disease causing characteristics since they control the overall biomass of bacteria and are generally parasites.

These phyla can be further subdivided into for different types: flagellates, amoebae, sporozoans and ciliates

flagellates: use flagella for propulsion

amoebae: move by cytoplasm

sporozoans: no means of propulsion and are all parasitic

ciliates: Have cillia and two types of nucleus

The phyla of Algae have very diverse bodies (unicellular, flat, long,etc) This subkingdom contains 5 different types of phylum: Chlorophyta, Rhodophyta, Phaeophyta, Pyrrophyta and Chrysophyta. This subkingdom lacks tissues and organs.

Finally the mold subkingdom .This mold subkingdom contains 4 different phylum: Myxomycota, Dictyostelida, Acrasid and Oomycota .These organisms are most closely related to fungi, as they have a cellulose based cell wall, but no chitin, which true fungi have. They also produce sexually and require the water to pass their gametes. At times these cells may gather in groups like a plasmodium, but their nuclei stay separated by the cells plasma membranes
