Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. The product of photosynthesis is mainly carbohydrates. Let's understand this in detail.

Photosynthesis Process

Photosynthesis takes place in the chloroplasts of the green plant cells. The process involves two main stages -

1. Light-dependent reaction: In this stage, light energy is converted into chemical energy and stored as ATP (Adenosine Triphosphate) and NADPH (Nicotinamide adenine dinucleotide phosphate). Water is also split into oxygen and hydrogen.

2. Light-independent reaction or Calvin cycle: In this stage, the ATP and NADPH generated in the first stage are used to fix carbon dioxide into glucose or other sugars. It is this stage that is responsible for the production of carbohydrates.

Product of Photosynthesis

The main product of photosynthesis is carbohydrates. Glucose is the primary carbohydrate produced by photosynthesis. Glucose is used by the plant cells for energy and also serves as the starting point for the synthesis of other organic compounds like cellulose, starch, and other sugars.

Apart from carbohydrates, photosynthesis also produces oxygen gas as a byproduct in the light-dependent stage.

Conclusion

Hence, the correct option is B - Carbohydrates. The product of photosynthesis is mainly carbohydrates, which is essential for the survival of the plant and other organisms further up the food chain.

The main product of photosynthesis is carbohydrates....hence B is correct
