Rooted floating plants have which of the following characteristics?

Rooted floating plants are characterized by being anchored to the sediment at the bottom of a water body, which allows them to access nutrients from the substrate. These plants typically have their leaves and flowers floating on the surface of the water, while their roots extend into the sediment. This configuration enables them to perform photosynthesis effectively by utilizing sunlight and exchanging gases with the atmosphere above the water.

The ability to anchor to the sediment also helps these plants withstand water currents and avoid being uprooted. Hence, the description of being attached to the sediment with leaves that float accurately defines the nature of rooted floating plants. Their growth strategy allows them to thrive in aquatic environments where they can benefit from both the water and the sediment.
