Would CAM plants have a lot of stomata? Why or why not?

No, they would have fewer stomata.


When a plant opens its stomata to collect carbon dioxide, the plant loses a lot of water through a process called transpiration. CAM plants usually are found in dry climates like deserts, so they want to conserve as much of their water as possible.

CAM plants do this by having relatively fewer stomata than C3 and C4 plants, as well as only opening their stomata during the night.

Hope this helps!
