Compare a multicellular green algae to an aquatic flowering plant?

Ulotrix – is a genus of multicellular green algae, found both in the seas and in fresh waters, forming an accumulation (mud) of light green or green color. The structure is filamentous, you can often find it while swimming in summer. Yellow capsule – aquatic plants that live for many years, grow in shallow bodies of water, slowly flowing lakes, are often found. The leaves are tough, have a large rounded shape. Yellow flowers, pleasantly smelling, in the middle there is a green “box”. The rhizome in water is green or yellowish in color. The difference between the first and second, first of all, is that the capsule is partially located on the surface of the water, and the algae are completely in it. Also, the capsule has an inflorescence. The common thing is that both are water inhabitants.
