Some plants known as ___ plants, like sugar cane and cacti, use different photosynthetic pathways, so that they can keep their stomata closed on hot days in order to conserve water.

Crassulacean acid metabolism or CAM plants

Explanation:

The plants in hot and humid climate perform a wasteful process called photorespiration as the Rubisco enzyme binds the oxygen.  The plants avoid this wasteful process by separating the steps of photosynthesis in a spatial and temporal way.

The cactus is known to avoid by separating the steps in a temporal way that is they close their stomata close during daytime abut open them at night time and inhale the carbon dioxide. The carbon dioxide is then converted into oxaloacetate.

This oxaloacetate is stored during night time and then used during the daytime by providing the carbon dioxide which undergoes the Calvin cycle and produces glucose molecules.

Thus, CAM plant is correct.
