  • What is Photosynthesis & Cellular Respiration?
  • Where does Photosynthesis & Cellular Respiration occur?
  • What are the responsibilities of each process? How are they related?
  • Photosynthesis is the process of which green plants and other organisms transform light energy into chemical energy. Light energy is used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Cellular respiration is the process through which cells convert sugars into energy.
  • Why is these process important?
  • Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.
  • Why do we need these processes everyday?
  • Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. They are related in the way that Photosynthesis is used in cellular respiration to make ATP.
  • How are these processes important to all organisms?
  • Without photosynthesis, the atmosphere would not have enough oxygen to support humans, animals and even plants, which also require oxygen. It also serves as the primary energy process for most trees and plants.
  • Living things need to use both ATP and glucose for energy which are produced through photosynthesis, and cellular respiration. These are molecules that organisms use for energy.
  • All organisms need glucose because it is stable to transport but it is also to powerful for cells to use so it is then broken down into the smaller ATP that they can use for energy.
