hey here is your answer
These plants are seaweeds and "Seaweed" is actually a misnomer because the word "weed" implies that it is a plant. However, because it lacks the vascular system common to all plants, seaweed is actually considered a form of algae. Seaweed can be split into three major groups: green algae, brown algae and red algae, all of which conduct photosynthesis differently.
Green Algae
Closer than any other kind of seaweed to vascular plants, green algae get their color from chlorophyll pigments, predominantly chlorophyll a and b. Both types of chlorophyll absorb mostly shorter, red wavelengths of light that have a tough time penetrating deeper waters.
Brown Algae
Brown algae do contain chlorophyll, they predominantly contain the photosynthetic pigment fucoxanthin, which reflects yellow light.
Red Algae
Red algae can comprise the majority of seaweed species. Although these organisms contain chlorophyll, they get their unique coloration from their two accessory pigments: the bluish phycocyanin and the reddish phycoerythrin. These pigments absorb longer, bluish wavelengths of light and this allows them to grow in deep waters where longer wavelengths of light can penetrate.
