In this photograph of a horizontal cutting of the lower part of the blade (under an optic microscope) we can distinguish very well the medulla, the cortex and the meristoderm of F. spiralis. We can also see, by the disposition of the cells, some specialization and formation of proto-tissues.

Fucus spiralis is a species of seaweed, a brown alga (Heterokontophyta, Phaeophyceae), living on the littoral shore of the Atlantic coasts of Europe and North America. It has the common names of spiral wrack and flat wrack.
