Protista Kingdom is divided into three groups:

Plantae, plant like: those that have the ability to photosynthesis and are autotrophic; they produce their own foods. They live in soil, on the barks of trees, in fresh water, an in salt water. Plant-like protists are very important to the earth because they produce an abundant amount of oxygen. They are the basis for the aquatic food chain.
 Animalia, animal like: those that are heterotrophic meaning they have to eat other food sources. They have to go out and find their food. A lot of them have some kind of locomotion or mobility.
Fungi, fungus-like: those that are heterotrophic by absorption, meaning they absorb their food through their cell walls. They usually grow towards their food as well.

If you are not a plant, animal, fungi or bacteria then you are thrown into the Kingdom Protista. They are mostly unicellular organisms, but there are multicellular Protista as well. They are microscopic. Some are capable of photosynthesis. They are important producers in our environment especially in marine and fresh water ecosystems.

Examples of each group:
1. Plantae, plant-like: Euglenoids, Dinoflagellates (planton), Chrysophytes (Green Algae), Red Algae and Brown Algae (kelp).
2. Fungi, fungus-like: Slime molds, downy mildew and water molds 
3. Animalia, animal-like: Trypanosome, Giardia, Trichonympha, Amoebas (Amoebic dysentery & primary amoebic meningoencephalitis), a harmless Paramecium and malaria causing Plasmodium.
