Each type of seaweed is rich in its own unique set of nutrients: 1  Nori seaweed has the highest amount of protein compared to the other types. 2  Wakame has the highest amount of calcium. 3  Sea Lettuce is very high in iron. 4  Hijiki is high in calcium and fiber.
Many of these algae are very ancient organisms, and although lumped together as algae, are not really very closely related, having representatives in 4 of the 5 or 6 kingdoms of organisms. Seaweeds are far more complex organisms than generally realised.Many have specialised tissues and growth forms.They may have very complicated sex, with many of them producing sex pheremones (chemicals that attract males or male gametes), and with many different types of sex organs.eaweeds are far more complex organisms than generally realised.
