Because of moon and the night flying insects like moths pollinate them so they open at night only

Why is the size of stoma smaller in the night?
stomata only open during the day and close at night becasue plants only photosynthesis during the day cos they need the sun which isn't visible 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.
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 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 is the refference of why is it that only plants can photosynthesize?
As well as plants, some bacteria also photosynthesize, though they use a different chemical process. Some plants use different photosynthetic mechanisms, known as C3, C4, and CAM. The latter mechanism is used by plants (such as some 'perching plants') that may have a water conservation problem. These plants open their stomata at night to take in CO2, and dissolve that in a specific chemical. During the day, they close their stomata to conserve water, and process the stored CO2 to produce sugars, etc.
Why do wood sorrel plants flowers only open at night?
Because, as small inconspicuous white flowers, the only pollinators who can find them are moths, and moths come out at night, when they are more obvious.
Why do bluebells flowers only open at night?
Because plants that flower at night are usually pollinated by night flying insects like moths.

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. 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.

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.

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.
How many stomata are likely to 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.
