Photosynthesis and metabolism: In this video, we convey the importance of photosynthesis as a metabolic pathway. Without the igniting fuel of the suns rays, life on Earth as we know it would cease to exist. Through the light-dependent and light-independent reactions of photosynthesis, the metabolic cycle is fueled; this cycle consists of photosynthesis, glycolysis and aerobic resipiration. Through photolysis in the light-dependent reaction, the oxygen we breathe is released and the ATP that is needed to further fuel the cycle is produced. Without this oxygen, or without photosynthesis, life would return to an anaerobic environment like the primordial soup.

The Unity of Living Systems: All cellular organisms — prokaryotic and eukaryotic — share basic chemical similarities. Out of these similarities, however, emerge diverse patterns of cell assembly. Students encounter the tools to understand various cell types and their relationship to non cell entities such as viruses.

Metabolism: The metabolic pathways that produce energy create important environmental transformations. Although living organisms have diverse ways of meeting their energy needs, there is an amazing similarity between all life forms as they carry out metabolism directed to the construction and use of necessary biological molecules.

Sustainable Agriculture: Curing America's Eating Disorder: The alternative to the longstanding American food policy of "cheap and lots" is to eat locally, eat seasonally and eat organic. Filmmaker Bonnie Bucqueroux and her dog Schmoopsie look at the sustainable agriculture movement, including a visit to Michigan State University's Student Organic Farm, where Dr. John Biernbaum discusses the options people have to grow their own food or to buy from local growers.

What the Deal with Organic Foods? Part 1: What is the difference between organic food and conventional food? Is organic really more healthy for you? The USDA lays out certain guidelines that farms have to follow in order to be able to claim the food is organic. In this video Natalie discusses what each of those guidelines are. What is surprising to learn is some of the growing practices of conventional farming and food processing. As an example, chemical plants and waste water treatment facilities will actually sell their toxic waist to conventional farms to use for fertilizer.
