True or False: Organisms belonging to kingdom Protista can only be unicellular.

This question is asking us about members of kingdom Protista. Kingdom Protista, or the protist kingdom, is one of five kingdoms of life into which all living organisms can be classified. The five kingdoms are plant, fungus, animal, protist, and Monera, also called bacteria.

Members of the animal, plant, fungus, and protist kingdom are all eukaryotic organisms. This means that their cells possess a nucleus and other membrane-bound organelles. Members of kingdom Monera are all prokaryotes, which means that their cells do not possess a nucleus or other membrane-bound organelles.

All members of the animal kingdom, like fish, birds, and humans, are multicellular organisms. The prefix multi- means many. Multicellular organisms are made of many cells. All plants are also multicellular. Fungi can be unicellular or multicellular. The prefix uni- means one. Since all prokaryotic organisms are unicellular, members of the kingdom Monera are all unicellular. Protists, like fungi, can be unicellular or multicellular. Examples of unicellular protists include amoebas and euglenas. Examples of multicellular protists include many types of algae, including giant kelp.

We know that protists can be unicellular or multicellular. That means this statement is false.
