C3 and C4 plants(1) stomata stay open all day and close at night. CAM plants(2) stomata open during the morning and close slightly at noon and then open again in the evening.

The most important benefit of CAM to the plant is the ability to leave most leaf stomata closed during the day. [9] Plants employing CAM are most common in arid environments, where water is scarce. Being able to keep stomata closed during the hottest and driest part of the day reduces the loss of water through evapotranspiration , allowing such ...
Guard cells have cell walls of varying thickness(its inner region, adjacent to the stomatal pore is thicker and highly cutinized [7]) and differently oriented cellulose microfibers, causing them to bend outward when they are turgid, which in turn, causes stomata to open. Stomata close when there is an osmotic loss of water, occurring from the ...

They are bordered by guard cells. The stomata open when the turgor pressure increases in the guard cells, causing the cells to buckle outward.

Experts say that the window of 9:30 a.m. to 11 a.m. may be the best time to consume coffee.
[4] [6] During the following day, stomata are closed, malate is decarboxylated, and CO 2 is fixed by RuBisCO. This process alone is similar to that of C4 plants and yields characteristic C4 fractionation values of approximately -11‰. [6] However, in the afternoon, CAM plants may open their stomata and perform C3 photosynthesis. [6]
