Final answer:
During photosynthesis, plants produce glucose and oxygen. Glucose is used as an energy source and stored as carbohydrates, while oxygen is a byproduct released into the atmosphere.
Step-by-step explanation:
Plants produce glucose and oxygen during photosynthesis that are the reactants of the process of cellular respiration.
Photosynthesis is the fundamental process by which plants utilize carbon dioxide, water, and sunlight to create glucose, a type of carbohydrate, and oxygen. This glucose serves as a vital energy source for plants and can be stored as large carbohydrate molecules like starch. Oxygen, on the other hand, is considered a byproduct of photosynthesis and is essential for animal life as it is released into the atmosphere.
The primary structures responsible for photosynthesis are chloroplasts within the plant cells. They convert solar energy into chemical energy contained within glucose. Carbohydrates made from photosynthesis are utilized by living organisms, including the plants themselves, as a primary energy source.
