The light-independent reactions of photosynthesis, also known as the Calvin cycle, take place in the stroma of the chloroplast.

Here's a breakdown:

* Chloroplasts: These are the organelles in plant cells where photosynthesis occurs.

* Stroma: The stroma is the fluid-filled space surrounding the thylakoid membranes within the chloroplast. It's where the enzymes and molecules needed for the Calvin cycle are located.

The light-dependent reactions, on the other hand, occur within the thylakoid membranes of the chloroplast.
