Question

Quizplus · Accepted Answer

Holdfasts are structures that attach seaweeds to a substrate, such as rocks or the ocean floor. A seaweed that floats freely on the surface of deep bodies of water would not need holdfasts as they do not attach to anything. Thalli, blades, bladders, and gel-forming polysaccharides are all structures commonly found in seaweeds, but holdfasts would not be expected in a free-floating seaweed.
