Branches on the tree of life: the biology of algae
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 an...
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...
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; ...
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...
Visualizing cell processes: photosynthesis and cellular respiration
Through live action and animated models, this program illustrates the basic biochemical processes involved in photosynthesis and cellular respiration. Cellular Respiration Topics: Glycolysis and Fermentation, Mitochondrion Structure, Aerobic Respira...
Branches on the tree of life: the biology of chordates
The Phylum Chordata includes tunicates, sea lancelets, hagfish, and all familiar vertebrate animals. This program explores how these seemingly diverse animals evolved and how the group is unified by four characteristic structures: a hollow dorsal ne...
