Detailed explanation-1: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Detailed explanation-2: -Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Detailed explanation-3: -Cellular respiration: inputs – glucose, oxygen. Outputs – carbon dioxide, energy, water. Photosynthesis: inputs – light energy, carbon dioxide, water. Outputs – glucose, oxygen.

Detailed explanation-4: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Detailed explanation-5: -Photosynthesis is how plants combine light, water, and carbon dioxide to produce energy (glucose) and oxygen. The glucose powers the plants functions, and the oxygen is released back into the atmosphere. Cellular respiration is how animals combine glucose and oxygen to produce carbon dioxide and water.
