Plant-like seaweeds known as algae
In Biology. The only type of multicellular protists are plant-like seaweeds  known as algae. There are three different types of algae that are  differentiated by color. The brown algae … is known as Phaeophyta,  the red algae is known as Rhodophyta, and the green algae is known  as Chlorophyta. In Biology.

TargetDriver. 1 Most of the organisms are unicellular, some are colonial and some are multicellular like algae. 2  Most of the protists live in water, some in moist soil or even the body of human and plants. 3  These organisms are eukaryotic, since they have a membrane bound nucleus and endomembrane systems. The majority of organisms classified as protists are unicellular though there are a few multicellular organisms. For example, kelp (“seaweed”) is technically a protist even though it is multicellular. Kelp is not grouped with plants, however, because it lacks the cellular complexity present in plant cells.

Kingdom Protista is a diverse group of eukaryotic organisms. Protists are unicellular, some are colonial or multicellular, they do not have specialized tissue organization. The simple cellular organization distinguishes the protists from other eukaryotes. The cell body of the protists contain have a nucleus which is well defined and membrane bound organelles. Volvox is one of several multicellular protists. This is kelp, a multicellular algae: Mycoprotists, or fungus-like protists, have characteristics of fungus cells. Examples: Water molds, which are unicellular, and cellular slime molds, which are unicellular and multicellular at different stages of their life cycle.
