First, different morphological characteristics

Kelp morphological characteristics: Kelp is a brown algal plant intermediate between bacteria higher plants. The algal body is a long, flat leaf, brown-green, generally 1.5 ~ 3m long, 15 ~ 25cm wide, the longest can reach 6m, the width can reach 50cm.

Morphological characteristics of laver: The number of cell layers of algal body of the subgenus Of true laver is 1, each cell contains 1 stellate pigment body, which belongs to species of Laver in China.


Second, the distribution area is different

Distribution areas: 1, kelp seaweed algae belong to subfrigid zone, is the north Pacific unique local species, the Atlantic has some seaweed distribution, kelp are mostly distributed in the northern hemisphere, the southern hemisphere also have a small amount of distribution, more commonly grown in subtidal zone undersea rock, kelp growth was mainly affected by temperature, light, nutrient plant hormone, so on factors. The Pacific Northwest is home to most of the world's kelp species.

2. Nori distribution area: although nori species are distributed in frigid zone, temperate zone, subtropical zone tropical zone, species diversity in subtropical to temperate zone is rich. Nori in China also follow the geographical distribution of this law, mainly distributed in the Yellow Sea Bohai Sea to the southeast coast of the intertidal zone.


Three, the nutrient composition is different

1. Nutrients of kelp: Kelp is rich in seaweed polysaccharides, mainly including alginate, fucose gum alginate. contains acid polysaccharide kind material, fucus galactosaccharide sulfate, macrophylla algin, galacturonic acid, amino acid, taurine, bifidobacterium other active components.

2. Nori nutrition: Nori is rich in protein, carbohydrate, unsaturated fatty acid, vitamins minerals, has high nutritional value.
