Honey, if you were really a scientist you'd know how to spell the names correctly. You can go to dictionary.com and read the definitions to find the differences.

A protozoan is a single celled animal. ("proto-" from Greek for first, "zoo-" for animal).
An example would be an ameba or a paramecium. There are many kinds. The old system of classification called a protozoan a protist, but "protist" is now often seen as an artificial category. All of the single celled organisms with nuclei in their cells got tossed into the catch-all category of protist, whether they were plants, animals, fungi, or something else.
"Normal" animal cells, that is, like from a multicellular organism like yourself, cannot live and reproduce independently. Protozoa can, though. Their internal structure will have much in common with your own cells.

A protozoan is a one-celled, animal-like, heterotrophic protist.

2. with flagella: Trypanosoma, ...
3. with pseudopodia: Amoeba, ...
