Location of Photosynthesis Machinery in Chloroplasts
The below video mentions the thylakoid and the stroma as key components for photosynthesis reactions in the chloroplast:
As we saw in the video, the thylakoids are stacked on top of each other throughout the center of the chloroplast, while the stroma fills the space between the thylakoid and the inner membrane.
Photosynthesis can be broken down into light and dark reactions. Light-dependent reactions occur in the thylakoid, while light-independent reactions occur in the stroma.
