Final answer:
Plants produce glucose and oxygen during photosynthesis, which are used as the reactants in cellular respiration.
Step-by-step explanation:
Plants produce glucose and oxygen during photosynthesis. These are the reactants in the process of cellular respiration. Photosynthesis is a crucial biological process where plants use sunlight, carbon dioxide (CO2), and water (H2O) to produce glucose (C6H12O6), which serves as energy storage, and oxygen, which is a byproduct released into the atmosphere. Cellular respiration then uses the glucose and oxygen to produce energy for the plant's cellular activities, emitting carbon dioxide and water as byproducts.
During photosynthesis, plants produce glucose and oxygen as the products. Glucose is a carbohydrate that serves as the food for plants, while oxygen is released into the atmosphere as a waste product. Glucose can be used by plants to store energy and can be combined with other glucose molecules to form larger carbohydrates such as starch. Without photosynthesis, there would not be enough oxygen in the atmosphere for animals to survive.
