These are the best protist's
An amoeba is a weird looking jelly sack that constantly changes its shape. The way it moves it extends its pseudo pod and it reproduces asexually. It flows around its food and ingests it.
It uses a flagellum to move, and it also uses photosynthesis to eat, and it reproduces sexually and that is what sets it apart from the other three.
It moves there cilia rythymtically and brings food into an oral groove. It reproduces asexually and has two nuclei.
