DNA sequence data for diplomonad, euglenozoan, a plant and an unidentified protist suggest that the unidentified species is mostly closely related to the diplomonad. Further studies reveal that the unknown species has fully functional mitochondria. Based on these data, at what point on the Phylogenetic tree given in Figure 25.9 “Exploring Eukaryotic Diversity”, in the textbook, did the mystery protists lineage probably diverge from other eukaryotic lineages. Introduction: The diplomonads are the group of flagella containing organisms and are mostly parasitic in nature. They are placed under zooflagellates within kingdom protista. Euglenozoa are unicellular large group of flagellate excavate that include free living species.

Question

DNA sequence data for a diplomonad, a euglenid, a plant, and an unidentified protist suggest that the unidentified species is most closely related to the diplomonad. Further studies reveal that the unknown species has fully functional mitochondria. Based on these data, at what point on the phylogenetic tree in Figure 1 did the mystery protist’s lineage probably diverge from other eukaryote lineages? Explain.

Answer 1

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Life cycle complexity Describe a generalized complex life cycle for a parasite that would encompass one or more intermediates hosts and multiple larval stages. Why would this heteroxenic life cycle be an evolutionary advantage over a monoxenic one?

Hello! Discuss the adaptations that plants and protists have evolved to invade and manipulate their hosts. ( one example of a plant and one of a protist). Thank youuu
