How Green Plants Make And Use Food (Rev. 1984)

All living things depend, directly or indirectly, on green plants for food and oxygen. This film clarifies the difference between food and raw materials, and the difference between photosynthesis and cellular respiration. We digitized and uploaded this film from the A/V Geeks 16mm Archive. Email us at footage@avgeeks.com if you have questions about the footage and are interested in using it in your project.
