The above restrictions also seem to apply to other macroalgae… Macroalgae are multicellular marine plants that are easily observed by the unaided eye and whose “thallus” (plant body) is characterized by holdfasts for attachment, and by “laminae,” reproductive “sori,” gas bladders, and/or stipes. As a consequence, much needs to be done in terms of the physiology, molecular biology, metabolic engineering, and outdoor cultivation trials before their true potential is realized [160].
