About seaweed

"Seaweed", this product is the dried algal body of Sargassumpallidum (Turn.) C. Ag or Sheepshead Sargassumfusiforme (Harv.) Setch. of Sargassum family.

The former is habitually called "macroalgae", the latter is habitually called "microalgae"; it is an alga that grows in the sea, and is a cryptogamous plant of the plant kingdom, which comprises several different classes of photosynthesis-producing energy-generating organisms.

Seaweeds are generally considered to be simple plants, with the following main characteristics: no vascular tissue, with no true differentiation of roots, stems, or leaves; no flowers, fruits, or seeds; reproductive organs with no specialized protective tissues, often producing spores or gametes directly from a single cell; and no embryo formation.

A collective term for marine algae (Algae), usually anchored to the sea floor or to some solid structure, which are simple plants consisting of a single plant or a long series of basic cells.

Aquatic plants that occur in large numbers without stems or leaves.

The organisms that bear the name seaweed encompass a wide range of organisms that vary greatly in form, spanning a wide range of life forms, but **** have in common the fact that they live primarily in seawater and synthesize organic matter through pigmentation and photosynthesis in their own bodies.
