The main difference between Kale and Seaweed is that the Kale is a form of cabbage with green or purple leaves and Seaweed is a various types of algae.
Kale () or leaf cabbage is one of certain cultivars of cabbage (Brassica oleracea) grown for their edible leaves, although some are used as ornamentals. Kale plants have green or purple leaves, and the central leaves do not form a head (as with headed cabbage). Kales are considered to be closer to wild cabbage than most of the many domesticated forms of Brassica oleracea.
Seaweed, or macroalgae, refers to several species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing up to 90 percent of earth’s oxygen. Understanding these roles offers principles for conservation and sustainable use. Mechanical dredging of kelp, for instance, destroys the resource and dependent fisheries.
Seaweed are a source of biologically active compounds including proteins and polysaccharides with promising uses in nutrition, biomedicine, bioremediation and other uses.
