First three Science Project Panels

Storyboard Text

  • Yes! All of the sunlight is mine. And it rained yesterday so I have plenty of water for photosynthesis. And I also get plenty of carbon dioxide from all of the animals that live in this farm. Those are the three ingredients I need for photosynthesis, water, sunlight, and carbon dioxide. What happens is, all of those go into the leaves, separately and in their own unique ways. They all meet in the chloroplast where they are used in the light reactions and the Calvin cycle. The end products are glucose and oxygen. I use the glucose for myself, and I release the oxygen for all of the animals on the farm. The purpose of photosynthesis is to create energy for plants.
  • Now that photosynthesis has taken place, I have oxygen and glucose. I release the oxygen into the air, and use the glucose for food and energy, and to build more plant material. During photosynthesis, the light reaction uses light energy and water. They go into the thylakoids, which is in the chloroplast. The products of the light reaction are ATP energy and oxygen. The ATP goes over into the Calvin cycle. The Calvin Cycle takes place in the stroma, which is also in the chloroplast. The Calvin cycle uses the ATP energy to break down carbon dioxide and reorganize it into glucose. And I already told you what I do with the oxygen and the glucose.
  • Hey! Stop! What are you doing?
  • Why?
  • What is cellular respiration?
  • I need it for cellular respiration
  • I'm taking your glucose.
  • Cellular respiration uses the products of photosynthesis and uses them to make the reactants of photosynthesis. Cellular respiration takes place in the mitochondria and cytoplasm of the cell. It takes glucose and oxygen and turns them into carbon dioxide and water. These are then turned into ATP energy which I can use to do things. The equation for photosynthesis is the exact opposite of the equation for cellular respiration. The purpose of cellular respiration is to release the ATP energy that is stored in food.
  • So the equation for photosynthesis is:CO2 + H2O --> O2 + C6H12O6And the equation for cellular respiration is:C6H12O6 + O2 --> CO2 + H2O + ATP.
  • Yeah that's right. And for every one glucose molecule, 36 ATP is produced during cellular respiration.
  • Since the equations are opposites of each other, photosynthesis and cellular respiration work very well together. The products from photosynthesis are used in cellular respiration, and the products from cellular respiration are used in photosynthesis. Because of this, both of these are very important for the environment and every living thing that does one of them.
