If you are wondering do Plants Release Oxygen at Night? Can you grow them as houseplants for better indoor air? Find out the best ones in this article!
Whether Plants Release Oxygen at Night has been a heated topic of discussion for a long time. So, check out this article to know if it is true or just a myth!
Here are the most oxygen-producing trees in India
Do Plants Release Oxygen at Night?
During photosynthesis, plants absorb carbon dioxide from the surrounding air to make food and release oxygen into the surroundings. However, plants need sunlight for this, and at night, in the absence of sunlight, the process reverses and the plants start to respire just like human beings, that is, inhaling oxygen and exhaling CO2.
But, on contrary, there are certain plants, especially those belonging to arid regions like cactus and some tropical epiphytes that perform CAM (Crassulacean Acid Metabolism).
In CAM, plants open their stomata during nighttime to absorb CO2 to minimize water loss and store it in form of malate, which is utilized during the daytime in the kelvin cycle to make food in the presence of sunlight without the need for opening stomata.

Do CAM Plants Produce Oxygen at Night?
There has been a lot of research and discussion on CAM plants releasing oxygen, as the stomata is closed during the daytime. Many researchers reveal that when the stomata opens at night time, it releases oxygen. While some say that the oxygen diffuses from the membrane throughout the day and night.
Whether the CAM plants elevate oxygen levels or not, there is one guarantee that they absorb plenty of carbon dioxide from the air during the nighttime, thus making the surrounding air in the room much safer to breathe.
