Photosynthesis can be defined as a process, by which photosynthetic organisms produce their own food (in the form of sugars), by using carbon dioxide and water. During photosynthesis, oxygen is released as a byproduct.
Cellular respiration involves breakdown of complex biomolecules (such as sugars) to produce energy in the form of ATP molecules. During cellular respiration, carbon dioxide, along with water are released as byproducts.
Answer: The correct answer is- Photosynthesis produces oxygen, while cellular respiration produces carbon dioxide.
Photosynthesis is a process of formation of food (glucose) in green plants and algae using water and carbon dioxide in the presence of sunlight. It produces oxygen as waste product.
Cellular respiration is a metabolic process in which food (such as glucose) is oxidised to release energy in the form of ATP (adenosine triphosphate) that is used for various cellular activities. It produces carbon dioxide as a waste product.
