Which product is a result of the process of photosynthesis?

The process of photosynthesis primarily involves plants converting light energy, usually from the sun, into chemical energy in the form of sugar, specifically glucose. This occurs in the chloroplasts of plant cells, where carbon dioxide and water are used as raw materials. When plants take in carbon dioxide from the atmosphere and water from the soil, they utilize sunlight to drive the conversion of these substances into glucose and oxygen—this is the essential outcome of photosynthesis. The sugar produced serves as an energy source for the plant, allowing it to grow, reproduce, and carry out vital functions.

While oxygen is indeed a byproduct of photosynthesis, the focus of the question is on the primary product. Carbon dioxide and water are not products of the process; rather, they are essential inputs needed for photosynthesis to take place. Thus, the correct answer is sugar, as it is a direct result of the photosynthetic process.
