WebNov 6, 2024 · The c4 and cam photosynthesis pathways have evolved to minimize the process of photorespiration, which can be a significant problem in hot, dry conditions. By taking advantage of different leaf anatomy and physiology, these pathways allow the plant to keep its stomata open for longer periods of time and to use CO2 more efficiently. WebThe CAM pathway is adapted to minimise water loss and photorespiration. Examples of CAM plants include cactus, pineapple, etc. CAM Photosynthesis CAM pathway is adapted in plants to perform photosynthesis under stress. The CAM pathway reduces photorespiration.
