Seaweed lives on the surface of the water or on the bottom of the sea, why does seaweed concentrate

Large seaweeds grow on the seabed, and small ones such as kneolulis, euglena, and pear dinoflagellates are on the surface of the sea, and overblooming often causes red tides.

There are many types of seaweed, most of which grow on the seabed, and some species of planktonic seaweeds grow on the surface of the sea.

Seaweed is grown on the seabed.

Seaweeds are a large family, and with the exception of some macroalgae, many are very tiny plants, some of which are unicellular.

Seaweeds are algae that grow in the sea, and are cryptophytes of the plant kingdom, which includes several different organisms that produce energy similar to photosynthesis.

Chinese scientific name: seaweed.

Family: Sargassum family.

Other names: macrophylla, artemisia, sea root vegetables, seaweed.

Kingdom: Plantae.

Distribution: Grows in shallow areas below the low tide line - where the sea meets the land.

For example, kelp, seaweed, cauliflower, and seaweed are seaweeds.

An algae plant of the genus Inferior.

There are about 1,000 kinds of algae in the ocean, and there are about 50 kinds of seaweed that can be eaten along the coast of China, and the most edible ones are kelp, seaweed, wakame, etc.

Seaweed contains a certain amount of protein and a lot of polysaccharide cellulose, as well as a small amount of fat, rich in inorganic salts and vitamins. Seaweed is a low-calorie food, especially suitable for the elderly, people with high blood pressure, heart disease, diabetes and constipation. Kelp is the most iodine-containing food, with about grams per 100 grams, which is an ideal food for the prevention and treatment of goiter.

Coastal dwellers in many countries around the world have the habit of eating seaweed, and there are 21 kinds of seaweed used for daily cooking in the diet of the Japanese, which accounts for about 10% of the seaweed, and the amount of seaweed used in South Korea is even larger, and the Philippines, Indonesia, Myanmar, Vietnam, Thailand and other countries also have the habit of eating seaweed in large quantities.

Residents of the Nagashi village on the coast of Japan eat seaweed almost every day. Those who ate seaweed every day suffered from high blood pressure, constipation, and bowel cancer were significantly lower than those who did not eat it. Mr. Shoji Kondo, Professor Emeritus of Tohoku University in Japan, said, "One of the secrets of longevity is to eat kelp regularly. ”

A study by an American scholar pointed out that "the low incidence of breast cancer in Japan compared to the United States may be related to the fact that Japan often eats seaweed such as seaweed, wakame, and kelp, which may contain anti-cancer substances and ingredients that can lower cholesterol, as well as minerals ...... essential for health."

In recent years, seaweed drinks, seaweed salads, seaweed rolls, and other foods made from seaweed have been selling well in the U.S. market.

Seaweed grows in the shallow sea below the low tide line, where the sea meets the land, where the impact of the waves is relatively gentle, the water is rich in minerals, and the sun is abundant.

Whether it is red algae or brown algae, although they are different in color, they all contain chlorophyll, which can use sunlight for photosynthesis and make food. The reason why the sea world is so colorful and lively is due to the fact that the seaweed is indispensable.

As soon as the sun hits, marimo (commonly known as seaweed balls) will float to the surface; As soon as it gets dark, it sinks to the bottom of the lake again. Recently, scientists finally understood why the seaweed balls "make at sunrise and rest at sunset". You've probably seen a seaweed ball, a cute green ball.

Although the nickname is "seaweed ball", it has nothing to do with the sea.

In contrast, marimo, a freshwater, spherical green algae that floats in a ball wound in a filamentous or threaded pattern. Like other algae, they move with the current or rocks on the shore, absorbing the faint light to grow.
