Phaeophyta
Around 1,500 species and are common in cool marine waters. Some kelps yield algin, a chemical used as a smoothing or thickening agent in processing foods. Most species are attached to rocks by holdfasts but Sargassum Weed often floats in large mats.
"Brown algae. Multicellular marine plants characterized by the presence of chlorophyll a and c with fucoxanthin. The carbohydrate food reserve is laminarin. Motile cells are biflagellate, with one forward flagellum of the tinsel type and...

Rhodophyta
Red algae are small delicate marine species with some occuring in fresh water. All species contain chlorophyll, which would otherwise be green in color but it is masked by other pigments, most of which appear to be pink or purplish. Several species of red algae are used as a food source by humans.
"Primarily marine plants characterized by the presence of chlorophyll a and phycobilins....

Lichens
"Logically regarded as a another class of fungi, the lichens are mostly Ascomycetes that have obligate symbiotic relationships with unicellular algae which multiply within their densely packed hyphae. A very few lichens appear to involve Basidiomycetes. About 17,000 described species."

Basidiomycetes
Terrestrial fungi with the hyphae septate but the septa perforated; complete septa cut off reproductive bodies, such as spores or gametangia. Chitin is predominant in the cell walls. Sexual reproduction involves formation of basidia, in which meiosis takes place and on which the spores are borne. Basidiomycetes are dikaryotic during most of their life cycle, and there is often complex...
