The first step in photosynthesis is when CO2 and H2O enter the leaf through the stoma. This step is light dependent.
The second step is when light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2. This step is also light dependent.
The fifth step is when the ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose. This step is light independent
The sixth step is when the calvin cycle converts 3CO2 molecules from the atmosphere to glucose. This step is also light independent.
This is the calvin cycle, The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
