Seaweed

Phycologists consider seaweed to refer any of a large number of marine benthic algae that are multicellular, macrothallic (large-bodied), and thus differentiated from most algae that tend towards microscopic size (Smith, 1944). Seaweeds are found among the green, red, and brown algae. Some cyanobacteria may also be counted as seaweeds. Seaweeds are named after terrestrial "weeds", and are not to be confused with things like seagrass which are vascular plants and not algae.

Uses

Seaweeds are used extensively as food by coastal peoples, most particularly in Japan but also in Korea, in Peru and in the Canadian Maritimes. For example, nori is a dried red alga, formed into sheets, and used to wrap sushi. Irish moss is another red alga used in producing various food additives. Other seaweeds may be used as seaweed fertiliser.
