Which consequence occurs when a plant shifts from the C3 to the CAM photosynthetic pathway?

💡 Explanation

When a plant shifts to CAM, stomata close during the day to conserve water, reducing direct CO2 uptake via diffusion into mesophyll slowing down carbon fixation. Therefore assimilation rate decreases, rather than water use efficiency increasing or enhanced photorespiration/RuBisCO carboxylation, which are less important in this mechanism.
