Beginning at the edge of a pond and moving into the lab, striking photography reveals the fascinating micro-world of the protozoa. Live movement and stop-action shots capture the structures and functions of four of the main phyla as represented by the amoeba, paramecium, euglena and plasmodium. The live sequences of sexual and asexual reproduction of the paramecium are especially valuable. Follow-up questions at end of program. 30 minutes.
