Seagrasses are underwater plants that evolved from land plants. They are like terrestrial plants in that they have leaves, flowers, seeds, roots, and connective tissues, and they make their food through photosynthesis. Unlike terrestrial plants, however, they do not have strong stems to hold themselves up—instead, they’re supported by the buoyancy of the water that surrounds them. Seagrasses are a very important food source and habitat for wildlife.
The fun fact about seagrass is Seagrasses are not true grasses. They are more closely related to terrestrial lilies and gingers than grasses.
