Plant Aerenchyma

Large, interconnecting air gaps are anatomically known as aerenchyma and are present in the stem, root, and leaf of plants. It is a specialised tissue that makes it easier for gases and liquids to move around inside of plants. The breakdown of intercellular gaps inside plant tissue and the presence of air spaces that are related to one another result in the formation of aerenchyma. Providing an effective channel for oxygen diffusion for photosynthesis, respiration, and the transport of carbohydrates and other chemicals, it is an adaptation to the low oxygen concentrations in the soil. A plant's weight can be reduced via the development of aerenchyma, enabling it to float on water. Aerenchyma can aid in the healing of damaged tissue and lessen tissue damage brought on by waterlogging. Additionally, it is involved in the storage of metabolites such as sugars that aid plants in surviving adverse conditions.
