Wetland Plant Adaptations. - Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Totally submerged plants are the true water plants or hydrophytes. - Physiological adaptations permit the organism to perform special functions, for instance, making venom, secreting slime, phototropism, but also more general functions such as growth and development, temperature regulation, ionic balance and other aspects of homeostasis. Freshwater plants have adapted various types of leaves, depending on where they are located on the plant.

Wetland plants are generally classified into three main types: emergent, floating, or submerged. Two key adaptations they have are the ability to survive in waterlogged and anoxic (no oxygen) soil, and the ability to tolerate brackish waters.

Mangrove trees have become specialized to survive in the extreme conditions of estuaries. A plant that is growing in the dirt can pick up oxygen from air pockets in the dirt. Does producing oxygen as a by-product of photosynthesis mean that plants can live in anoxic soil? There are two species of cattail in Delaware; the broadleaf cattail is native (Typha latifolia), while the narrowleaf cattail (Typha angustifolia) is invasive.
