Web2.1.1 Canopy light transmission and photosynthesis in the ORCHIDEE trunk 115 The ORCHIDEE_DF model is base d on ORCHIDEE trunk version 5453 (updated in September 2024). A general description of the physical processes related to energy and water balance, vegetation dynamics and biogeochemical processes in ORCHIDEE can be found in Krinner … WebJul 30, 2024 · Photosynthesis takes place in two stages: light dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO 2. how does technology affect dating
