What is endosymbiosis and why is it considered to be the source of eukaryotic diversity? Why are we confident this only happened once? What is primary and secondary endosymbiosis? Was there another endosymbiotic event that led to a third lineage? What group of organisms possesses a structure that might suggest this possibility and what is the structure? Why is the structure in question different from the ancestor of other plastids?
Carotenoids in algae have evolved through primary and secondary endosymbiosis. provide a well-constructed phylogenetic tree to show where carotene, neoxanthin, zeaxanthin, violaxanthin, fucoxanthin, and lutein arose in the macrophytic, multicellular groups of algae. add descriptive and informative title to it
An analysis of the phylogeny of mutualistic and free-living fungi, as well as the rates of nucleotide substitutions in selected ribosomal RNA regions, was conducted with a view to determining how coevolution can drive changes in the heritable traits of a species. Which of the following is NOT the expected outcome of the study?
A. There was a faster rate of molecular evolution occuring among free-living fungal species compared to lichens.
B. Fungi coevolving with algae in lichens featured higher rates of nucleotide substitutions.
C. Higher rates of nucleotide substitution in mutualistic fungi were widespread across many sections of the genome.
D. The transition to mutualism accelerated the rate of molecular evolution for fungal species.

- What is special about the endosymbiotic events that gave us brown algae?arrow_forwardThe theory of the endosymbiotic origin of mitochondria and chloroplasts was first proposed by the biologist Lynn Which of the following statements provides support for the theory of endosymbiosis? 1. All the genes found in chloroplasts are homologous to genes found in the nucleus of eukaryotic cell. 2. Mitochondria contain their own ribosomes. 3. Proteins need a targeting sequence to be imported into a chloroplast. 4. Mitochondria can generate a proton gradient and harness it to synthesize ATP. O A. 1, 2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct.arrow_forwardWhich phylogenetic tree below represents the evolutionary history of the fungi based on the most recent data?

- What genes from the mitochondrion are also used for phylogenetic analysis? Can you name and describe atleast 2 genes?arrow_forwardWhich of the following is FALSE regarding phylogenetic trees? 1) The branch lengths on the tree are scaled to molecular (DNA) changes and/or time. 2)Phylogenetic trees have shown us that there is much more bacterial diversity compared to eukaryotes. 3) Phylogenetic trees show the evolutionary relatedness of different organisms. 4). The branch lengths on the tree depict abiotic and biotic factors affecting speciation.arrow_forwardThe universal phylogenetic tree of life shows the divergence of Bacteria, Archaea, and Eukarya. Studies of Lokiarchaeota help to elucidate these relationships, but the first universal tree of life was constructed by Carl Woese using ribosomal RNA sequences. There are advantages to using different types of nucleic acid for different types of analyses. What is a specific advantage of using small subunit ribosomal RNA (SSU rRNA) gene sequences for phylogenetic analysis compared with DNA sequences? ▸ View Available Hint(s) SSU rRNA sequences accumulate mutations more rapidly than protein-encoding DNA. SSU rRNA is frequently transferred through horizontal gene transfer, whereas DNA sequences are not. Primers are required in DNA sequence analysis, but not for SSU rRNA sequence analysis. Although PCR products can be visualized with SSU rRNA, this is not the case with other forms of nucleic acids. DNA sequences are too highly conserved to work well for sequence analysis; individual species are…arrow_forward
- Enumerate at least three evidences to support the occurence of primary and secondary endosymbiosis in some groups of eukaryotes.arrow_forwardRedraw the phylogeny of eukaryotes, expanded to show different members (e.g. dinoflagellates, diatoms) of the supergroups as necessary and indicate the location of the primary endosymbioses for mitochondria and chlorophyll on the phylogeny. Indicate the location of three secondary endosymbioses leading to chloroplasts and one location showing the loss of mitochondria on the same phylogeny.arrow_forwardGeneticists have determined the amount of DNA, the number of different genes, and the size of the cell/nucleus in a wide variety of model organisms. as we move up the phylogenetic scale, the amount of DNA/cell increases much more rapidly than does the volume in which that DNA must be packaged. How do higher organisms package their DNA in the interphase cell?arrow_forward
