Seaweed
Seaweed is a general term that is used to describe macroscopic, multicellular, benthic marine algae. Macroscopic means it is visible to the naked eye or at least using a basic microscope. Multicellular refers to organisms made up of more than a single cell.
Benthic organisms are those which live on or near the sea bed, and marine of course refers to sea water. The main requirements for seaweed to thrive are the presence of seawater or brackish water, and sunlight to enable photosynthesis. Seaweed is consumed in many coastal regions especially in East Asia.
