Seaweeds are not plants. They’re algae, without roots or leaves, although they do photosynthesize: harvesting the sun’s energy to build themselves. BUT there are a small number of real flowering plants in the sea: the seagrasses, which evolved from terrestrial plants and grow in large meadows.  Mostly water moves pollen around, but for at least one species, small crustaceans do the job of bees and carry sticky pollen from one plant to another.  Underwater gardening, anyone?  #Ocean #Seagrass
