The peepal tree (also known as the bo or bodhi tree) is frequently cited as a plant that produces oxygen 24 hours a day. Several sources reiterate this claim.
Plants Often Cited for 24-Hour Oxygen Production
While no plant produces significant net oxygen at night, some plants are highlighted for their relatively high oxygen production during daylight hours and lower rates of oxygen consumption at night, leading to a better oxygen balance compared to other plants. These include:
- Peepal Tree: This tree, sacred in Hinduism and Buddhism, is repeatedly mentioned as providing oxygen around the clock. [Reference: Multiple sources including Floweraura, Nurserylive]
- Snake Plant: This popular indoor plant is often listed as a top choice for nighttime oxygen production. [Reference: Leafylifestyle, FNP]
- Pothos: Also known as devil's ivy, this easy-to-care-for plant is cited as producing oxygen 24 hours. [Reference: ChhajedGarden]
- Other Plants Mentioned: Various sources list orchids, Areca palms, Tulsi (holy basil), and Christmas cactus as potential candidates for higher-than-average oxygen production, although the "24-hour" claim isn't consistently supported. [Reference: FNP, Nurserylive]
Important Clarification: Photosynthesis and Respiration
It's crucial to understand that all plants perform both photosynthesis (producing oxygen during daylight) and respiration (consuming oxygen at night). The claim that certain plants produce oxygen "24 hours" is an oversimplification. These plants likely demonstrate a relatively smaller decrease in their oxygen production during nighttime respiration compared to other plants. However, the net amount of oxygen produced is still significantly higher during daylight hours.
Conclusion
While the exact mechanism by which the peepal tree and others might exhibit higher oxygen production isn't fully detailed in available sources, several sources consistently point to the peepal tree as a key example, alongside other plants like the snake plant and pothos. However, it is important to note that even the most efficient plants produce oxygen most effectively in the presence of sunlight during the day.
