Which sugar is produced through photosynthesis in plants?

The sugar produced through photosynthesis in plants is glucose. During the process of photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using sunlight energy. This reaction occurs primarily in the chloroplasts of plant cells and is facilitated by the pigment chlorophyll, which captures light energy.

Glucose serves as an essential energy source for the plant and is crucial for cellular respiration. Moreover, glucose can be used to synthesize other carbohydrates such as starch and cellulose, which are vital for plant structure and energy storage. While fructose and sucrose may also be present in plants, they are not the primary product of photosynthesis; they are often derived from glucose through further metabolic processes.

Lactose, a sugar found in milk, is not produced by plants at all, making glucose the most accurate choice for the product of photosynthesis.
