Protists: Animal-like Protists

The video tutorial explains the characteristics of protozoa, highlighting their lack of a cell wall and their heterotrophic nature. It introduces the four main groups of protozoa, focusing on sarcodines, particularly amoebas, which move and feed using pseudopods. The tutorial also discusses the challenge of water regulation in sarcodines and the function of the contractile vacuole in expelling excess water.

Identify the four main groups of protozoa.

Describe the structure and function of pseudopods in amoebas.
