Seaweed is a collective term for marine algae, usually found on the seafloor or on a solid structure of some kind, and occurring in large quantities as aquatic plants with no stems or leaves, and the organisms that go by the name of seaweeds encompass a wide range of organisms that vary widely in form and span a wide range of lifeforms, all of which live in seawater.

Common brown algae include the genera Macrocystis, Sargassum, and Chlamydomonas, with the Pacific and Antarctic genera Macrocystis and Chlamydomonas being some of the largest at more than 33 meters in length, while the genus Kelp is abundant along the Pacific coast and in the British Isles, and Chlamydomonas, a common species of the intertidal zone of the British Isles, floats on a balloon.

Properties of seaweed particles

"Seaweed" is the kelp, purslane, wakame, rockweed, and other marine algae, is the growth of algae in the sea, is the plant world's cryptogamous plants, algae, including a number of different classes of photosynthesis energy-generating organisms, there is no real roots, stems, and leaves of the phenomenon of differentiation, do not flower.

Seaweeds grow in shallow areas below the low-tide line - where the ocean meets the land - where the impact of the waves is gentler, the seawater is rich in minerals, and there is plenty of sunlight, so whether it's red or brown algae, they all contain chlorophyll, which can be utilized to photosynthesize and make food.

What does a seaweed pellet look like

Seaweeds are 15 to 40 centimeters long, branched and alternate, without spiny protrusions, the leaves are bar-shaped or fine spatulate, the apex is slightly inflated, hollow, the air sacs are axillary, fusiform or globular, and the sacs have a longer stalk, which is harder in texture.

Shape: Seaweeds are wrinkled and curled, black-brown, some are glaucous, the main stem is terete with conical protuberances, the main branches arise from both sides of the main stem, and the lateral branches arise from the leaf axils of the main branches with short, small, spinelike protuberances.

Leaves: seaweed leaves between the axils of the branchlets with the birth of striped leaves, air sacs black-brown, spherical or ovoid, some with a stalk, bluntly rounded tip, some with a fine mucronate, brittle texture, soft when moist, water-soaked expansion, fishy, taste slightly salty.

Color: high-quality seaweed particles full, uniform color; good seaweed color is dark red, a little like brown, the color is the same; and poor quality seaweed, sometimes there appear to be three colors

Seaweed particles role and value

Seaweed has a high industrial, agricultural, edible and medicinal value. Giant seaweed is a very important industrial raw materials, not only can be extracted or used to make iodine, potassium, fucoidan and a variety of industrial products, and can be used as a new bio-energy.
