Fruit-producing water plant?

Question

Are there any water plants that grow fruit that is meant to be eaten? I’m specifically interested in plants that are not rooted permanently to the earth but are mobile for at least part of their life cycle.

Answer 1

Yes, there are aquatic plants that produce edible fruits and are not permanently rooted. One notable example is the water caltrop (Trapa natans), which floats on the surface and produces a starchy, edible fruit commonly consumed in parts of Asia. Another is the lotus (Nelumbo nucifera), which grows in water and produces edible seeds and roots. While the lotus anchors itself in sediment, its leaves and flowers are mobile on the water surface. These plants are excellent examples of aquatic species with edible parts and varying degrees of mobility during their life cycle.
