| [[http://https://en.wikipedia.org/wiki/Seaweed|Seaweed]] is the common name for marine plants and algae that grow in saltwater, mainly on the seacoast, and can attain a length of up to fifty meters. Their appearance is diverse and ranges from voluminous kelp leaves to herbaceous algae. There are red and brown algae, and bladderwrack. The algae, attaching itself to rocks and other hard surfaces, grows on solid ground in the sea. These aquatic plants filter pollutants from the water and release oxygen into the water. One square meter of seaweed can produce up to fifteen liters of oxygen per day, and its roots aerate the seafloor. | [[http://https://en.wikipedia.org/wiki/Seaweed|Seaweed]] is the common name for marine plants and algae that grow in saltwater, mainly on the seacoast, and can attain a length of up to fifty meters.

Unlike seaweed, seagrasses produce flowers and seeds. They grow in large underwater meadows on the ocean floor and absorb carbon dioxide (CO2). Similar to trees that absorb carbon dioxide from the air, seagrasses capture large amounts of it from the atmosphere.
