Question

how do photosynthesis and cellular respiration work together? they are not related photosynthesis makes oxygen and glucose; respiration uses them to make energy. both only happen in plants both only happen in animals

Explanation:

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Cellular respiration is the process by which cells break down glucose and oxygen to produce energy (ATP), carbon dioxide, and water. So, photosynthesis provides the glucose and oxygen that are used in cellular respiration. Option 1 is incorrect as they are related. Option 3 is wrong because cellular respiration happens in both plants and animals. Option 4 is incorrect as photosynthesis mainly occurs in plants (some bacteria also do it but not animals).

Answer:

Photosynthesis makes oxygen and glucose; respiration uses them to make energy.
