The term algae is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates: red algae (plastids with chlorophyll A); diatoms, yellow-brown algae and brown algae (chlorophylls A and C); and green algae (chlorophylls A and B). This program explores the diversity, structure, ecological roles and modern classification of these vital primary producers.

The diversity of rotifers is stunning, and this program shows many different species. Planktonic rotifers have special adaptations for open water life. Nematodes (round worms) include a number of important human parasites, seldom seen but easily found. Thirteen common rotifer species illustrated this diverse group. Tree moss, leaf litter, and compost piles swarm with nematodes.
