Seaweed Guide

It is estimated that there are 6 to 7 hundred different seaweed species around the coasts of Britain. This is a guide to the more common, larger species. Seaweeds are attached to rocks by a holdfast. This anchors them to rocks, and does not extract nutrients as does the root of a land plant. The stipe is the stem of the plant, and the main body is known as the frond or the blade. The brown colour of seaweeds is due to the chemical fucoxanthin. As sea water absorbs light from the red end of the spectrum, chlorophyll is not as efficient at absorbing light energy as with land plants.
