Photosynthesis not only produces sugars, but also amino acids, so now the products of photosynthesis are defined as organic matter (namely (CH2O) in the new curriculum standard textbook).

As for upstairs, it is wrong to say that starch is glucose and glucose is starch.

In fact, when sugar is synthesized by photosynthesis, glucose with simple structure is first synthesized, and then glucose is polymerized (dehydrated) into starch and stored.

It can be understood that starch is the storage form of glucose.
