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.
Differentiate the functions of the macro-and micronuclei of ciliates. What is the advantage of having dimorphic nuclei as compared to the monomorphic nucleus of other protozoans?
Apicomplexans are widespread and common parasites of worms, echinoderms, insects, and vertebrates (including humans). What characteristics do these protozoans have that make them highly infective (efficient as parasites)?
How can foram fossils provide clues about past cold and warm periods, and global temperature change?
What characteristics separate Euglenozoans from Chlorophytes (i.e., Volvox, green algae)?
The Phylum Animalia has some unique traits that set it apart from plants and fungi. Check all traits that animals have:
[] They have teeth [] A blastula is formed shortly after fertilization [] They are all cute and furry [] Prokaryotic Cells [] Eukaryotic cells[] They are all noctumal[] Multicellular[] They are all nocturnal[] Motile at some point in their lives[] No cell wall

- In the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions: Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. 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_forwardAmoebas and foraminferans are distantly related protists.

- Jr. Scientist discovers a never-before-classified protist. It contains multinucleated filaments, similar to fungal hyphae however, upon closer examination the cell walls are found to be composed of cellulose rather than chitin.
