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 p..
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; Organel..
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 pinocyt..
The biology classics: paramecium, hydra, planaria, daphnia
Understanding the amazing phenomena of life requires an intimate acquaintance with living things. This new program introduces students to four organisms we call the Biology Classics, “classics” not only because they..
The biology of lakes, ponds, streams, and wetlands
Open Water Environments: Adaptations for planktonic life are observed in Daphnia and other cladocerans, copepods, rotifers, and planktonic algae. Bottom Environment: Explores bacterial decomposition, recycling of materia..
The biology of seashores
In these programs life is examined in terms of habitat, diversity, adaptation, ecological niches, and interrelationships. Modular presentation, stunning biological photography, and up-to-date learning design create a pow..
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 ..
The light microscope: window on the microcosm
This program demonstrates techniques for using a student microscope to achieve spectacular images. Emphasis is on correct lighting procedures and the techniques required for viewing living cells.
