The light dependent reaction helps to make ATP and NADPH, the “batteries”. Those are then given to the stroma for the light independent reaction, which makes the sugar, of photosynthesis. Good luck!
The difference between light dependent and light independent reactions is light independent is energy from sunlight that is absorbed by Chlorophyll. Also light dependent is energy that is converted into stored chemical energy. In the independent reactions, the chemical energy basically harvests during the light dependent reactions, which drives the assembly of these sugar molecules from carbon dioxide.
