Detailed explanation-1: -Basically aerenchyma is parenchyma tissue in aquatic plants. The cells of aerenchyma make a network which has wide air spaces or air cavities for gaseous exchange. These air cavities make the plant light and buoyant and hence, plants can float easily in water.

Detailed explanation-2: -Aerenchyma is a spongy tissue with large intercellular air spaces that is found in aquatic plants. It provides buoyancy and allows the circulation of gases.

Detailed explanation-3: -Aerenchyma is a spongy tissue that forms spaces/air channels in the leaves, stems, and roots of halophytic plants (Santos et al., 2016). The presence of aerenchymatic tissues helps in exchange of gases between the shoot and the root systems.

Detailed explanation-4: -Aerenchyma is a modified parenchymatous tissue containing air chambers between cells. Function: These cells facilitate the diffusion of gasses between the plant and its surroundings and provide buoyancy to aquatic plants.

Detailed explanation-5: -Aerenchyma is the term given to plant tissues containing enlarged gas spaces exceeding those commonly found as intracellular spaces. It is formed in the roots and shoots of wetland species and in some dryland species in adverse conditions, either constitutively or because of abiotic stress.
