Do Cactus Produce Oxygen?

Cacti, just like any other plant, produce oxygen. Due to their unique stance, people seldom doubt their ability to produce oxygen. Another popular query is—how much oxygen do these produce? Let us check out the probable answer here.

Cacti are unique stem succulents that store water in their stems. They have distinctive growing shapes that are generally globular or cylindrical. They are found in arid and semi-arid areas that are usually not accessible. Cacti are considered wonderful decorative pieces. Plant lovers always prefer adding cacti to their indoor collections. 

Cacti produce oxygen just like any other plant. They produce oxygen in the form of O2 from the process of photosynthesis—the process by which plants make their food from sunlight. 

How Much Oxygen Does Cactus Produce?

Cacti produce oxygen after photosynthesis. This is because they have the ability to absorb sunlight. They absorb water from the soil and combine sunlight, water, and carbon dioxide to create glucose and oxygen. What makes a cactus different from other plants is its positioning of stomata in them. In general, plants have stomata in their leaves that facilitate the exchange of gases through the opening of their pores. In cacti, stomata are present in the stems; however, the function is the same as that of others.  

We can easily interpret that cacti produce oxygen just like any other plant. However, how much oxygen does the Cactus produce? This is an interesting question. 

Cacti produce oxygen, however, not in such significant amounts that would improve the levels in the room. The amount of oxygen produced by a cactus is almost negligible. You would need hundreds of such cacti to produce an ample amount of oxygen. 

The stomata in Cactus have a unique feature of opening at night instead of the day—this facilitates their survival in harsh weather conditions. This feature of cacti can be considered as we select them to adorn our houses. At night, having cacti in the bedroom can improve the levels of oxygen. Something is always better than nothing. 

Do Cactus Purify Air?

Cactus produces oxygen after photosynthesis. This makes this plant capable of increasing the atmosphere in the home. Purification of air is something that makes Cactus stand out among other indoor plants. Having decontaminating plants in the house is ideal for the purification of air. Among various options available, cacti are mostly the best option. 

Do Mini Cacti Purify The Air?

Mini Cactus is ideal for decorative purposes. There are many other underlying advantages of the same. When placed on the table on television or computer, Cactus may act towards protecting from the harmful electromagnetic rays. 

Not only this, cacti in the home can absorb many invisible chemical compounds around us, thus making air pure around us. You can get cacti that are proven to purify the air around you. 

Some cacti that purify air are:

Having an exciting combination of cacti and other species can make the work many folds better.  That combination that has the ability to absorb more will make the air purer. 

Do Cacti Produce Oxygen At Night?

Plants, in general, do not perform photosynthesis at night, because of the absence of sunlight. However, there are a few species like orchards, areca palms, and Succulents that are able to produce oxygen even at nighttime. They are able to perform photosynthesis at night because of a unique process, which is called CAM, that is, Crassulacean acid metabolism. This process allows the stomata of the plant to open at night so that all the carbon dioxide is absorbed in, and there is thus gas exchange before sunrise. Moreover, since cactus do not have leaves, the stems perform photosynthesis for this succulent.

Thus these plants are good to keep at home, boosting the amount of fresh air. Since cacti are stem Succulents, therefore, Yes, cacti would produce oxygen at night.
