Adaptations to Aquatic Environments Aquatic plants evolved from terrestrial plants. Like whales and other marine mammals, aquatic plants evolved from land back to aquatic habitats. Aquatic plants modified terrestrial features to withstand emerged, submerged,or floating conditions. The plant elongates and forms fatty acids from the ethylene.
Ethylene is a common gas in swamps due to decay.
Production of buoyant sees that float on high unflooded ground. Seeds germinate while still attached to the plant. As the water gets deeper, the wavelength of light gets shorter until its gone. Organs specialized to excrete salts -selectively remove certain ions from the vascular tissus of the leaf. Its three leaves and anthers form a sailboat.
