Hannah Kim Photosynthesis and Cellular Respiration Discussion Questions 1. Plants probably do more photosynthesis in a year because in order for cellular respiration to take place, photosynthesis is crucial. 2. Plants use carbohydrates while animals use lipids for their primary energy storage molecule. Carbohydrates (starch and glycogen) provide less energy than that of lipids. Hence, while this amount of energy is efficient for plants, it is not enough for animals with their higher metabolic needs. Lipids store about 9kcal/g, which is about twice that of carbohydrates. 3. Plants have to convert solar energy to chemical energy because they cannot directly use the sun’s energy. Hence, they have to construct their own carbohydrates in photosynthesis so that they can use the energy from breaking them down. 4. 5. 6. Plants must have sunlight in order to survive. Without sunlight, photosynthesis cannot occur and thus, the plant cannot do cellular respiration. 7.
