Compare the phylogenetic tree of protists with the secondary endosymbiosis theory which proposes how photosynthetic protists evolved. Are both reconcilable? Explain.
We discussed two theories of the evolution of multicellularity in the animals, the Colonial Theory and the Syncytial Theory. For each of the two theories, give a brief summary of the theory and describe the characteristics you would expect to find in the protist ancestor proposed by each theory.

- What is a working definition of a “protist”?arrow_forwardExplain why protists are not considered a clade.arrow_forwardModern taxonomic treatments rely heavily on phylogenetic data to classify organisms. In the past, taxonomists often used a morphological species concept, in which species were defined based on similarities in growth form. Give an example of how a morphological species concept would group a set of protists differently from how a phylogenetic species concept would.arrow_forward
- Under what category Cladonia rangiferina comes?arrow_forwardProtista 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 Falsearrow_forwardWhy is 'protists' considered a polyphyletic grouping? Why do biologists still use it?arrow_forward
- Which group is correctly paired with its description? A. diatoms-important consumers in aquatic communities B. diplomonads-protists with modified mitochondria C. apicomplexans -producers with intricate life cycles D. red algae-acquired plastids by secondary endosymbiosisarrow_forwardWhich type of protist shows characteristics that make it difficult to classify as either plant-like or animal-like? 1.Diatom 2.Amoeba 3.Euglenoid 4.Ciliatesarrow_forwardGive some characteristics of kingdom-II protista?arrow_forward
