C3 plants use the Calvin cycle for carbon fixation, while C4 plants possess a unique mechanism that allows them to synthesize a 4-carbon compound prior to the Calvin cycle, increasing efficiency in hot conditions. C4 plants also reduce photorespiration, which improves their adaptability to drought. These differences highlight how various plants have evolved strategies to optimize photosynthesis based on their environments. ;
C3 plants fix carbon through the Calvin cycle directly, while C4 plants capture CO2 to create a 4-carbon compound before entering the Calvin cycle, enhancing efficiency in hot climates. C4 plants also reduce photorespiration, making them better suited for arid conditions. These adaptations showcase how different plants optimize photosynthesis according to their environments.
