In daylight, plants take water, sunlight, and CO2 from its atmosphere and generate oxygen in return. Sunlight is an essential element for photosynthesis. That is why in the night, plants carry out respiration only, i.e. inhaling oxygen O2 and releasing carbon dioxide CO2.
But there are some plants with exceptional cases. These are the plants that perform photosynthesis at night as well.
This kind of photosynthesis is distinguished as Crassulacean Acid Metabolism CAM. CAM primarily occurred in desert plants that live on other plants for a living.
These plants do not open their stomata in daylight and store water. In the night they open their stomata and use the carbon dioxide and store them in the form of malate. Later they breakdown this malate to produce sugar like in photosynthesis.
But the oxygen they provide in the night is much less than the oxygen produced by photosynthesis in daylight. So, the CAM process in plants depends upon different factors like whether they can store water or they are an epiphyte or not.
