Availability information for this program

The Biology of... series of core curriculum programs explores the "deep branches" on the tree of life to reveal a modern view of the classification and phylogeny of each group studied in the biology curricula. The narrated programs feature new techniques of microscopy, animation, and photography to reveal the structure, process, and behavior in living things.


  • Algae

    The term algae is a catchall for several evolutionary lines of phytosynthetic organisms: dinoflagellates; red algae, diatoms, yellow-brown algae, and brown algae. This program treats diversity, structure and ecolgical roles of these vital aquatic producers.

  • Fungi

    This program explores the structure, life cycles, classification and evolutionary relationships of four major lines of fungi: Chytrids, Zygomycetes (mold), Ascomycetes (cup fungi) and Basidiomycetes ( mushrooms). Also covered are the fungi imperfecti --a grab bag of asexual species, difficult to assign to any of the major lines of fungi evolution.

  • Bacteria

    Compelling microscopy of living bacteria highlights structure, physiology, behavior and the vital roles these microbes play in the biosphere, including oxygen production (cyanobacteria), decomposition and nitrogen fixation.

  • Plants

    A general introduction to the members of the green kingdom and their life cycles. Major groups include mosses, liverworts, ferns, horsetails, and the seed plants (gymnosperms and flowering plants). Clear graphic animation is used to describe the molecular level of mechanisms of photosynthesis.
