Yes, the Peepal tree does give off oxygen at night. Unlike most other trees that undergo respiration at night and release carbon dioxide, the Peepal tree is unique in its ability to release oxygen both during the day and night.

The reason behind the Peepal tree’s continuous oxygen production lies in its special stomata called sunken, giant, or hydathode. These stomata are present on the lower leaf epidermis of the tree. These sunken stomata allow the tree to absorb carbon dioxide during the day for photosynthesis while minimizing water loss.
During the day, the Peepal tree carries out photosynthesis, a process in which it uses sunlight, water, and carbon dioxide to produce oxygen and glucose. This is the primary source of oxygen production by the tree during daylight hours.
However, what sets the Peepal tree apart is its ability to continue releasing oxygen even at night. While most plants close their stomata during the night to conserve water, the Peepal tree’s sunken stomata remain open. This means that the tree can still perform a limited form of photosynthesis called Crassulacean Acid Metabolism (CAM), absorbing carbon dioxide at night and releasing oxygen as a byproduct.
It is worth noting that the oxygen produced by a single Peepal tree is quite minimal compared to the oxygen produced by a dense forest or a vast expanse of plants. Nevertheless, the continuous oxygen release by the Peepal tree, even at night, contributes to air quality and provides a significant benefit to its surroundings.
As a result of its continuous oxygen production, the Peepal tree holds special significance in many Indian communities. It is often regarded as sacred and is commonly found near temples or other places of worship. The belief in its ability to give off oxygen day and night further adds to its symbolism and reverence in these cultures.
In conclusion, the Peepal tree does give off oxygen at night. Its unique sunken stomata allow it to keep its leaf pores open during the night, enabling the tree to continue absorbing carbon dioxide and releasing oxygen through a process called CAM. This continuous oxygen production makes the Peepal tree an important contributor to air quality and a revered symbol in various communities.
