Types of Photosynthesis in Plants: C3, C4, and CAM

The video revisits photosynthesis, focusing on the differences between C3, C4, and CAM pathways. C3 photosynthesis is common but inefficient in dry environments due to photorespiration. C4 plants, like corn, use a four-carbon compound to continue photosynthesis even when stomata are closed, showing convergent evolution. CAM plants, such as cacti, open stomata at night to conserve water, storing CO2 for daytime use. These adaptations help plants balance photosynthesis and water conservation in arid conditions.
