Which group includes plants that grow entirely underwater?

Which group includes plants that grow entirely underwater?

• A. Emergent Plants
• B. Limnetic Zone
• C. Floating Plants
• D. Submerged Plants

Answer: (D)

Submerged plants are the ones that stay completely underwater; they are adapted to live with all their leaves and stems under the water and are often rooted in the sediment. Emergent plants have parts that rise above the water surface, even though their roots may be underwater. Floating plants sit on the water surface, with leaves that float and roots often not supporting the plant in the sediment. The limnetic zone is a depth-related open-water area, not a plant growth form. So, the group that includes plants growing entirely underwater is submerged plants.
