Solution
Organs of aquatic plants are made of a special parenchyma tissue known as aerenchyma. It consists of a network of parenchyma cells which enclose very large air cavities. These air cavities store gases and make the aquatic plants light and buoyant. Collenchyma is a simple permanent tissue with pectocellulose thickening in its wall and no intercellular gaps.
