Light-dependent Reactions

Wikipedia

Light-independent Reactions

•The Calvin Cycle – dark reactions which take in CO₂ and form sucrose and starch

•CAM photosynthesis - process used with plants that don’t require much water, such as succulents and cacti (example of plant adaptation to the environment)
