Detailed explanation-1: -Answer: Aquatic plants have well developed Aerenchyma system. Aerenchyma is a spongy tissue that form space or air channels in root, stem and leaves. This allows exchange of gases between shoot and root.
Detailed explanation-2: -Aerenchyma is found in aquatic plants or hydrophytes and wetlands.
Detailed explanation-3: -Leaves, fruits and flowers are the regions where the parenchyma tissue is present. It is often called ground or fundamental tissue and makes up the mesophyll (internal layers) of leaves, the cortex (outer layers) and pith (innermost layers) of stems and roots; it also forms the soft tissues of fruits.
Detailed explanation-4: -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.
Detailed explanation-5: -Collenchyma tissues are involved in providing structural support to the stem, leaves etc. Aerenchyma is present only in the aquatic plants which help in the floating of the plant.
