These information-rich programs take an entertaining route in examining both the inner workings of the cell and the ways intercellular reactions occur. With extremely clear graphics and a witty narrative, the whole array of cellular organelles is presented, as well as the structure and function of the cell membrane.

The two programs are:

KEEPING IT TOGETHER: Cell Membranes
With all the activities inside and outside the cell, how does the cell membrane hold it all together? This program closely examines the structure and function of cell membranes, including compartmentalization, intercellular interaction, regulation of the movement of materials, and as a location for biochemical activities. Using a combination of narration, film footage, and engaging graphics, the program covers the various ways in which materials can cross the cell membrane, such as diffusion, active and passive transport, osmosis, and endo- and exocytosis. The effects of osmosis - plasmolysis and turgor in plants - are also presented. 33 minutes

INSIDE CELLS: Cells and Their Organelles
Take your biology students on a tour of an unusual art museum-the "Cell Gallery." Using electron microscope images and entertaining graphics, this program walks viewers through the basic components of a cell. The tour looks in detail at the structure and function of cellular organelles, including cell membranes, nuclei, mitochondria, chloroplasts, smooth and rough endoplasmic reticula, ribosomes, lysosomes, vacuoles, cytoplasm, cytosol and cytoskeleton, microtubules and microfilaments, and the Golgi complex. The program also covers the importance of internal cellular membranes and compares the relative sizes of the different organelles. 29 minutes
