The term "algae" refers to a class of mainly aquatic, photosynthetic, and nucleus-bearing organisms that lack the real roots, stems, and leaves of plants as well as their specialized multicellular reproductive structures.
Fucus is a brown alga and it belongs to the Phaeophyta class.
These algae species can be found practically anywhere along the world's stony seashores.
They have a tremendous economic benefit, as they are widely used in pharmaceutical companies for the development of drugs to treat iodine shortage, obesity, thyroid problems, and a variety of other nutritional deficiencies.
