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.

Which plants keep their stomata open only at night?
In most green plants the stomata are only open during the day. They allow carbon dioxide to reach the cells where the majority of photosynthesis takes place. As they also allow transpiration (water loss) the stomata of most plants close during the night when photosynthesis is not possible. There is a group of mainly desert plants known as CAM plants. These carry out a process called Crassulacean acid metabolism, which effectively allows them to store carbon dioxide in their leaves. In these plants the stomata are normally closed during the day to prevent water loss when temperatures are high, and open during the night when temperatures are lower.
Why do wood sorrel plants only open at night?
Wood sorrel plants do not only open at night; they follow a circadian rhythm where their flowers open during the day and close at night. This pattern is likely related to attracting specific pollinators, such as bees and butterflies, that are active during the day. The opening and closing of flowers also help protect the reproductive structures from environmental factors like rain and wind.
Why does the stomata of a desert plant close during the day?
In desert plants, the stomata is open during night. During night, desert plants (also called xerophytes) absorb co2 and form an intermediate. Then during day time when the stomata is closed to prevent loss of water, they use this stored carbon dioxide to perform photosynthesis.
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 time of day would you exspect the stomata on a plant to be open or closed?
at night when there is little to no light.
What do CAM plants open during the day and close 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.

Is it true that guard cells of non desert plants often close during the daytime and open at night to conserve water?
The guard cells of non desert plants simply contract a bit but do not close. Desert plants close their guard cells.
Why do plants do opposite breathing at night?
Many plants, called C3 and C4 plants, open their stomas during the day to let in carbon dioxide to instigate the process of cellular respiration. However some plants called CAM plants open their stomas at night. The main reason for this process is due to the physical environment the plants are located in. The majority of CAM plants are located in hot, dry and desert environments where water is scarce. As a result the CAM plants evolved so that they could close their stomas during the day and open them at night, to help retain water, at night the plants can still absorb CO2. Some examples of CAM plants are, cacti, pineapples, and aloe.

When do guard cells open and close in desert plants?
Guard cells in desert plants typically open during the night to take in carbon dioxide for photosynthesis, as cooler temperatures and higher humidity during the night allow for efficient gas exchange. They usually close during the day to conserve water and prevent excess water loss due to the hot and dry conditions in the desert environment.
Why do some plants open their stomata by night instead by day?
Very few of them do open at night -- In most green plants the stomata are only open during the day. They allow carbon dioxide to reach the cells where the majority of photosynthesis takes place.

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.
