Question 1 Report

Plants with breathing roots are characteristic features of vegetation in
Answer Details
Plants with breathing roots are characteristic features of vegetation in saltwater swamp. In saltwater swamps, the soil is often waterlogged with high salt content, and oxygen levels can be low. Therefore, plants in these regions have evolved special adaptations to survive in such conditions, such as breathing roots, which are roots that grow above the water surface to allow the exchange of gases between the atmosphere and the root system. This adaptation helps the plants to obtain oxygen from the air and remove excess carbon dioxide and other gases from the roots. Examples of plants with breathing roots found in saltwater swamps include mangroves and some species of palms.
