Protists are a group of (mostly) single cell organisms that are likely to be found in a drop of pond water, although many live in other very diverse environments. This is not a big topic within this Intensive, yet the anatomy of the amoeba, paramecium, and euglena is learned.
Amoeba: moves and eats using pseudopods
Paramecium: moves and eats using cilia
Euglena: can photosynthesize and moves using flagella
