I think it's lights-dependent reaction
Explanation:
Because the light dependent reaction use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier nadph in Plants, the light reaction take place in the thylakoid membranes of organelles has called chloroplast.
 
        
             
        
        
        
They both are encased organelle compartments inside a cell but A vacuole is the vesicle found within a cytoplasm of a cell. The vacuole contains some fluid. A lysosome, on the other hand, is an organelle found within the cytoplasm of eukaryotic cells.
