What happens to ordinary plants (or C4 or CAM) when stomata close?

What do cam plants close?
Their stomata during the day!.
. CAM plants close their during the day and open them at night?
stomata
What happens to ordinary plants not C4 or CAM when stomata close?
Simply oxygen or carbon di oxide stop coming in. But the extra gases that need to be given out are simply diffused out through cuticle or other epidermal layers.
What plants close stoma to control transpiration?
Plants can close their stomata to reduce water loss during times of stress using mechanisms like the accumulation of ions that cause osmotic changes, as well as the production of abscisic acid which signals stomatal closure. Additionally, certain plants, like succulents and CAM plants, have specialized adaptations that allow them to limit water loss by keeping their stomata closed during the day and opening them at night.

CAM plants close their what during the day and open them at night?
Cam plants close during the night and open during the day because they are photosensitive and respond to light. To do it experimentally, try with a torch for some time.
What do leaves go through at night?
At night, the leaves of C3 plants close their stomata and wait until the sunlight. For CAM plants, this is when the plants open their stomata and allow the carbon dioxide to come in.

How does CO2 get into a leaf?
Through the stomata, openings in the leaf surface. By diffusion. There are three photosynthesis processes, C3, C4, and CAM. (These names describe part of the chemistry.) The desert plants (and some epiphytes) use CAM, for in this process, the stomata are closed during the day, and open at night. The plant absorbs CO2 into its system as a complex chemical (the CAM bit) over night, and during the day, the stomata close and the plant converts the CAM chemical into CO2 to be used for photosynthesis in the usual way. Normal plants open their stomata during the day, and CO2 diffuses in and O2 out.
What does a CAM plant do?
Slows water loss by opening stomata only at night
Why do some plants close their stomata at night?
At night, there is no light, therefore no photosynthesis (which is the process of making energy from light). Photosynthesis uses CO2, however since photosynthesis is not occurring at night, there is no need to acquire CO2.Some plants (CAM plants) only open their stomata at night, however, in order to take in CO2 and store it until it is light and they can use photosynthesis then. This helps to eliminate water loss through the stomata which would occur more rapidly if the stomata were open during a hot day. (therefore, most CAM plants are found in desserts and such)
What happens to the oxygen produced by the Calvin cycle in CAM plants during the day, when their stomata is closed?
It is widely known that CAM plants open their stomata at night time to fix the CO2 in form of organic acids. However, during the light reactions in daytime O2 is evolved while the stomata are closed and there is no way out. The question goes to the possible mechanism by which these plants can handle this high oxygen level during the daytime, while the stomata are closed. Do these plants have an oxygen accumulation and release system like that of CO2? Is such a mechanism studied or described elsewhere?
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called?
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called CAM (Crassulacean Acid Metabolism) plants. CAM plants have adapted their carbon fixation process to avoid water loss during the day by keeping stomata closed, and perform photosynthesis during the night when conditions are cooler and less water loss occurs.
