Figure 16.20C_216.21 EVOLUTION CONNECTION: Multicellularityevolved several times in eukaryotes The origin of the eukaryotic cell led to anevolutionary radiation of new forms of life. Unicellular protists are much more diverse in formthan simpler prokaryotes.© 2012 Pearson Education, Inc.16.21 EVOLUTION CONNECTION: Multicellularityevolved several times in eukaryotes Multicellular organisms (seaweeds, plants,animals, and most fungi) are fundamentallydifferent from unicellular organisms.– A multicellular organism has various specialized cellsthat perform different functions and are interdependent.– All of life’s activities occur within a single cell inunicellular organisms.16.21 EVOLUTION CONNECTION: Multicellularityevolved several times in eukaryotes Multicellular organisms have evolved from threedifferent lineages:– brown algae evolved from chromalveolates,– fungi and animals evolved from unikonts, and– red algae and green algae evolved from achaeplastids.© 2012 Pearson Education, Inc.© 2012 Pearson Education, Inc.Figure 16.21AAncestral eukaryoteArchaeplastids UnikontsGreen algaeRed algaeOther green algaeCharophytesLand plantsAmoebozoansNucleariidsFungi16.21 EVOLUTION CONNECTION: Multicellularityevolved several times in eukaryotes One hypothesis states that two separate unikontlineages led to fungi and animals, diverging morethan 1 billion years ago. A combination of morphological and molecularevidence suggests that choanoflagellates are theclosest living protist relative of animals.KeyAll unicellularBoth unicellularand multicellularAll multicellularChoanoflagellatesAnimals© 2012 Pearson Education, Inc.25
