Video Summary

Photosynthesis and cellular respiration are two important processes that are essential for life. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Cellular respiration is the process by which organisms use oxygen and glucose to produce ATP, which is a molecule that cells use for energy. The waste product of photosynthesis is oxygen, which is used in cellular respiration. The waste product of cellular respiration is carbon dioxide, which is used in photosynthesis. This cycle of photosynthesis and cellular respiration is essential for life on Earth.
