Biologists have long been aware that the defunct kingdom protista is paraphyletic. whichof these statements is both true and consistent with this conclusion? a) many species within this kingdom were once classified as monerans. b) animals, plants, and fungi arose from different protist ancestors. c) the eukaryotic condition has evolved only once among the protists, and alleukaryotes are descendants of that first eukaryotic cell. d) chloroplasts among various protists are similar to those found in prokaryotes. e) some protists, all animals, and all fungi share a protist common ancestor, but theseprotists, animals, and fungi are currently assigned to three different kingdoms.

The correct answer is option E

The kingdom Protista includes large diversity of organisms ranging from flagellated cells to macroscopic organisms. It is sometime referred as Protoctista instead of Protista. Some of the ancient Protista’s have characteristics of animal and plant kingdom. For example Lichen is not a protist but it includes the characteristics of both Protista and Fungi. Likewise organisms such as algae, bacteria, ciliates have the features of Protist as all these are Eukaryotic cells. Since the formation of kingdom Protista many animals have been included and excluded from the kingdom. Even today red and brown algae are considered as protist
