Depends on the algae. Roughly speaking (this is not exhaustive), these are some of the major algal groups: Green algae - Aquatic relatives of plants. Red algae - Similar to green algae, but containing a red pigment. Brown algae - Many-celled aquatic algae, including kelp. Golden algae - Single-celled "plants" that form glass shells around them. Also called diatoms. Fire algae - Flagellate algae that whirl around when swimming. Also called dinoflagellates.
