The first stable product of the Calvin cycle has:

What is the source of oxygen present in the structure of glucose produced during photosynthesis?

The dark reaction of photosynthesis takes place in:

How many turns of the Calvin cycle are required to form one hexose molecule?

The thylakoids are removed and kept in a culture medium containing $CO_2$ and $H_2O$. If the setup is exposed to light,hexose sugars are not formed as the end product. The most appropriate reason for this is that

In photosynthesis,$CO_2$ combines with.........
