Tue or False: Most fungi secondarily lack flagellated cells in their life history and this places the monophyly of the supergroup to which they belong, in doubt, as these extant fungi no longer have the synapomorphy of the supergroup
Protista is no longer accepted as a Kingdom because the organisms classified as protists show varying degrees of genetic relatedness. Protista is a paraphyletic grouping that historically encompassed organisms that did not fit into other classification groups. Select one: O True O False
