Question

My question is why glucose is converted into starch in plants? I mean I know glucose is soluble and starch is insoluble. So that's why, if glucose is in a plant cell it might swell up. And if starch is there instead, the cell doesn't swell up. But why in case of starch, the cell doesn't swell up? Thanks in advance.

Answer 1

Glucose is the immediate product of photosynthesis which is utilised by the plant and extra glucose is stored in form of starch in the leaves. As glucose gets utilised so its presence cannot be detected. But starch is stored in plants and it can be easily detected, hence production of starch is often used as a measure of photosynthesis in leaves.

So, the correct option is 'Glucose formed in photosynthesis soon gets converted into starch'.
