Branches on the tree of life: the biology of arthropods
Phylum Arthropoda is the most luxuriant branch on the tree of life. This program covers phylum characteristic and three major arthropod classes: Crustaceans (copepods, waterfleas, branchiopods, decapods, and barnacles), Chelicerates (scorpions, pse...
The domains of life: life's three great branches
The Domains of Life updates the five kingdoms classification scheme with the latest understanding of life’s organization based on DNA, fossil, and biochemical evidence. Concise animations and superb microscope footage of primitive cells show event...
Inside the living cell: how cells obtain energy
Describes the fundamental role of ATP in providing energy for all cell work. Examines the two deeply interrelated and biochemically similar processes of aerobic respiration and photosynthesis, and discusses the structure and function of chloroplast...

Topics: A Variety of Cells, Cell Organization, Overview of Organic Molecules, Prokaryotic Cells, The Evolution of Eukaryotic Cells.
Inside the living cell: the cell - unit of life
This program shows the kinds of cells and emphasizes the fact that all cells have a common organization and how all cells carry out similar biochemical processes. Content: The Discovery of Cells; Cell Structures; Organelle Function; Cell Varieties; ...
Branches on the tree of life: the biology of molluscs
Phylum Mollusca is the second most diverse phylum of animals, with over 100,000 known species. First examined are the basic characteristics of the phylum - a soft body, muscular foot, mantle cavity with gill, and hard calcified shell. The four mos...
Inside the living cell: the outer envelope
Here students become acquainted with the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drink in fluids by pinocytosis. Content: Membrane Struc...
Inside the living cell: how cells are controlled
This program describes the genetic code, and how genetic instructions carried on DNA are transcribed into RNA. Explains how genes dictate enzymes and how enzymes produce specific reactions in cell processes. This highly visual tour of the processe...
Inside the living cell: how cells reproduce
This program discusses how DNA replicates, how copy errors occur and are remedied by repair enzymes, and how DNA is compressed into chromosomes making possible mitosis and cell division. This highly visual tour of the processes that keep life opera...
