Here's why:
* Chloroplasts: These are the organelles in plant cells where photosynthesis takes place.
* Stroma: This is the fluid-filled space inside the chloroplast, surrounding the thylakoid membranes. It contains enzymes and other molecules necessary for the light-independent reactions.
The light-dependent reactions occur in the thylakoid membranes within the chloroplast, where they capture light energy to produce ATP and NADPH. These products are then used in the stroma for the Calvin cycle.
