What makes the kingdom Protista unique?
Protists are single-celled.
Protists do not share a common ancestor.
Protists share a common ancestor with fungi only.
Protists are not made of cells.
Protists are single-celled.
The correct answer is: Protists are single-celled.
Protists are a diverse group of eukaryotic microorganisms that are characterized by being single-celled organisms. Unlike multicellular organisms, protists consist of a single cell that performs all the functions necessary for life. This makes protists unique among the other kingdoms of life, such as animals, plants, and fungi, which are typically composed of multiple cells. Therefore, the fact that protists are single-celled is what makes them unique.
