\nIn aquatic plants, large air sacs or cavities that provide buoyancy are modifications of parenchyma tissue. This specialized parenchyma tissue with extensive intercellular air spaces is called aerenchyma. Aerenchyma facilitates gas exchange in submerged tissues and provides buoyancy, allowing the plant to float or remain upright in water.

\nAerenchyma, a type of parenchyma tissue characterized by large air spaces, provides buoyancy and aids gas exchange in aquatic plants.
\n<\/section>\n
\nCollenchyma provides mechanical support to growing parts of the plant. Sclerenchyma provides rigid support and mechanical strength to mature parts of the plant. Complex tissues like xylem and phloem are responsible for transport of water, minerals, and food.
