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.
Multicellular animals are thought to have evolved from single-celledprotists resembling the choanoflagellates that exist today. Describesome specific advantages to multicellularity that gave animals anadvantage over their single-celled relatives.

Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments. Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments. Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments. Non-filamentous cyanobacteria generally produce spores…arrow_forward
- Protists are the most varied group of organisms that we studied this term. They display unique adaptations in feeding, reproduction, and lifestyle (parasitism, free living, etc) among many others!
