Answer:
1. Light-dependent stage
2. Light-independent stage or Calvin cycle
Step-by-step explanation:
Photosynthesis is the process by which plants and other autotrophic organisms synthesize their food (glucose) in the presence of sunlight as energy source. However, this photosynthetic process, which is a metabolic reaction occurs in two stages namely; Light-dependent stage and Light-independent stage.
- The light dependent stage occurs in the thylakoid membrane of the chloroplast. It involves the synthesis of NADPH and ATP needed for the light independent stage of photosynthesis.
- The light independent stage also known as Calvin cycle occurs in the stroma of the chloroplast. This is the stage where glucose is synthesized using inorganic source of carbon (CO2).
