You see an entire pond, with the same plant across most of it. The plant seems to be surviving very well. Which adaptation does
faust18 [17]

They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticles on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants.
