It is a common belief in communities across India that the Peepal tree, also known as Ficus religiosa, produces oxygen day and night. This belief stems from the understanding that the Peepal tree possesses a unique type of stomata.

Stomata are microscopic pores found on the surface of leaves that allow for gas exchange between the plant and its surroundings, including the exchange of oxygen and carbon dioxide during the process of photosynthesis. Most plants have stomata that open during the day and close at night.
The Peepal tree, however, is said to have a special type of stomata called sunken, giant, or hydathode, which are located on the lower leaf epidermis. These stomata are believed to remain open throughout the day and night, allowing the Peepal tree to continue producing oxygen even during nighttime when other plants may have closed stomata.
While the belief that the Peepal tree produces oxygen at night is widely held, it is important to note that scientific studies specifically examining this claim are limited. Most research on oxygen production by plants focuses on their overall contribution to the atmosphere and does not specifically investigate night-time oxygen production.
However, it is well-established that during photosynthesis, plants absorb carbon dioxide and release oxygen as a byproduct. This process occurs during daylight hours when plants have access to sunlight to fuel photosynthesis. It is during this time that the majority of oxygen production by plants takes place.
At night, in the absence of sunlight, plants generally undergo a process called respiration, where they take in oxygen and release carbon dioxide, similar to animals. This suggests that the Peepal tree, like most plants, would typically consume oxygen at night rather than produce it.
In conclusion, while it is widely believed that the Peepal tree produces oxygen day and night due to the presence of specialized stomata, scientific studies specifically examining this claim are limited. It is generally understood that most plants, including the Peepal tree, primarily produce oxygen during daylight hours through photosynthesis. During the night, plants typically consume oxygen through respiration.
