During photosynthesis, what does the carbohydrate get converted to?

The correct answer is starch.

Carbohydrates produced during photosynthesis are stored in the plant cells as starch, which is a complex carbohydrate made up of many glucose molecules. Starch is an excellent storage molecule for plants because it is insoluble and does not cause osmotic imbalances within the cell. While lipids and proteins can also be synthesized from carbohydrates, they are not the primary product of photosynthesis.
