Question
Chapter 26.2, Problem 2C
Summary Introduction
To determine: The kinds of scientific evidence that support the hypothesis that protists are a paraphyletic group.
Introduction: Paraphyletic taxon is defined by “shared ancestral characters” and includes a common ancestor but not all its descendants. They share only a few evolutionary relationships.

Group of answer choices Some protists are mixotrophic Certain protists share a common ancestor with land plants Some protists are photosynthetic prokaryotes which are similar to the ancestral chloroplast Protists are a polyphyletic group of organisms that often bear little resemblance to each other Although most protists are unicellular, some protists are multicellular as wellarrow_forwardProtista is no longer accepted as a Kingdom because the organisms classified as protists show varying degrees of genetic relatedness.
