Through color animation, graphics, live action photography, and classroom experiments, this video gives students a clear understanding of the vital energy giving process of photosynthesis. Video reveals the chemical processes of both respiration and photosynthesis and the products that are produced: glucose and oxygen. An experiment with a variegated leaf is demonstrated showing that photosynthesis takes place in the green cells of leaves. Video describes the roles of the epidermis, mesophyll, chloroplasts and chlorophyll in photosynthesis.
