No, trees cannot breathe underwater in the same way that they do on land. Trees rely on oxygen to survive, which they obtain through tiny openings called stomata on their leaves. These stomata allow the exchange of gases, with the tree taking in carbon dioxide and releasing oxygen.

When trees are submerged underwater, their access to oxygen is limited. Most trees would not be able to survive prolonged periods in submerged conditions due to the lack of oxygen. However, there are some exceptions.
Certain species of trees, such as cypress and mangrove trees, have special adaptations that enable them to survive in submerged environments. These trees have developed specialized root systems that allow them to obtain oxygen from the air and survive in oxygen-depleted water. These roots may rise above the water’s surface, allowing the trees to access atmospheric oxygen.
Kelp forests are another example of living underwater forests. Kelp is a type of large brown algae that forms dense underwater forests in coastal areas. While kelp is not a tree, it serves a similar ecological role and can be considered an underwater forest. Kelp has adaptations that enable it to obtain oxygen from the water through special gas-filled structures called pneumatocysts.
In summary, while most trees cannot breathe underwater, there are certain species, like cypress, mangrove trees, and kelp, that have adaptations allowing them to survive in submerged environments. These adaptations include specialized roots or structures that enable these trees to access oxygen in oxygen-depleted water or obtain oxygen from the atmosphere.
