How is the structure of the chloroplast related to its functions?

Answer 1

The structure of the chloroplast is highly specialized to facilitate its role in photosynthesis. It contains thylakoid membranes, which are organized into stacks called grana, where light-dependent reactions occur, capturing sunlight and converting it into chemical energy. The stroma, the fluid-filled space surrounding the thylakoids, houses enzymes and molecules necessary for the Calvin cycle, where carbon fixation takes place. This compartmentalization allows for efficient energy conversion and synthesis of organic compounds.
