Seaweed

Seaweed is a loose, colloquial term encompassing macroscopic, multicellular, marine algae. The term includes some types of red, brown, and green algae. Seaweeds are not classified as plants, as they do not have roots, leaves, or vascular tissue, but they are still often referred to as such due to their physical resemblance to terrestrial plants. In Hebrew, seaweed is known as algaim yam (אלגאים ים). In Japanese, it is called kaiso (海藻), while in Korean, it is referred to as haesam (해조). Seaweeds have been a staple in coastal communities for centuries, serving as food, fertilizer, and even material for various industrial applications. They play a crucial role in marine ecosystems, providing habitat and food for a wide range of organisms. Seaweeds are also known for their high nutritional value, containing essential vitamins, minerals, and antioxidants.
