Concept explainers
To draw: The phylogenetic tree consisting of the several types of the protists, plants, algae, and the
Concept introduction: The phylogenetic tree alignment of the supergroup species of the protists, plants, and the algae consists of the placement of the species in the various groups. The branches represent the starting of the trees, roots, and the phylogenetic diversity and the distance of each species present in the group.
The broad spectrum of the antibiotic drugs is used for combating and controlling the infection caused by the growth and infection of various pathogenic strains of fungi, plants, prokaryotic bacteria, and small microbes. The ribosomal RNA sequence analysis of the genome is analyzed based on the homology and the similarity in the sequences present in the genome.
Given data: The given data include the names of the various protists in groups like the Excavata, SAR, Archaeplastida, Unikonta, amoebozoans, animals, choanoflagellates, fungi, and Nucleariida species.

- This chapter shows a phylogenetic tree for the three domains of life, which is based on DNA sequence data for rRNA and other genes. Which of the following answers concerning the phylogenetic relationships found within this tree is incorrect? View Available Hint(s)for Part A Euryarcheotes are found in the Archaea Diatoms, Tubulinids, and Euglenozoans belong to the domain Eukarya Forams, Fungi, and Chlamydias belong to the domain Eukarya. Spirochetes belong to the domain Bacteria Ciliates, Red Algae, and Plants belong to the domain Eukarya.arrow_forwardWhich of the following statements about eukaryotes is correct? - Eukaryotes are life forms that possess a nucleus in the cells. - Some cellular features, such as endoplasmic reticulum, is uniquely eukaryotic and is not shared with either bacteria or archaea. - It has been hypothesized that the first eukaryotic cell is a chimera between a bacterium and an archaeon. - During phylogenetic reconstruction, it is often found that eukaryotic genes that are responsible for information processing are more closely related to corresponding archaeal genes than to bacterial genes. - All of the abovearrow_forwardTell whether the statement is true or false. 1. The endosymbiont hypothesis state that prokaryotes evolved into eukaryotic cells 2. Eukaryotes contain organelles such as mitochondria and chloroplast 3. Organisms develop by a process known as spontaneous generation 4. Bacteria is an example of prokaryoric cwll 5. Prokaryote is a type of cell that has no nucleus and no cell membrane but has cytoplasmarrow_forward
- Archaea (formerly known as archaebacteria) is one of the three major divisions of living organisms; the other two are eubacteria and eukaryotes. Nanoarchaeum equitans is in the Archaea domain and has one of the smallest genomes known, about 0.5 Mb. How can an organism complete its life cycle with so little genetic material?arrow_forwardDNA 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.arrow_forwardThe TATA-binding protein (TBP) is thought to be necessary for transcription in all eukaryotic cell nuclei. Studies show that archaea, but not bacteria,have a protein structurally and functionally similar to TBP. What does this similarity suggest regarding the evolution of archaea, bacteria, and eukaryotes? How might knowledge of this similarity affect how systematists classify these organisms?arrow_forward
- The oldest unquestioned fossil cells (Choose any/all that apply/are correct.) Group of answer choices were prokaryotes (cells without a discrete nucleus) were found in the 3.2 byo Apex Chert were found in the 1.9 byo Gun Flint Chert were eukaryotes (cells with a discrete nucleus) were intertwined filaments of cellsarrow_forwardIchthyophthirius multifiliis - the etiologic agent of "ich". Life Cycle What role do each of the following play? Organelle of Lieberkunn perforatorium mucocystarrow_forwardBacteriorhodopsin, and retinal, are part of a transmembrane complex that uses of sunlight to create a proton gradient, for synthesis of ATP from ADP, in which of the following organisms? one of the members of the Archaeobacterial kingdom one of the members of the Eubacterial kingdom (ancestral to the mitochondria) one of the members of the Animal kingdom one of the members of the Eubacterial kingdom (ancestral to the chloroplasts) one of the members of the Plant kingdomarrow_forward
- Describe the Theory of Endosymbiosis. a) Briefly define the Endosymbiotic Theory. 2 pts,b) Explain why the Theory of Endosymbiosis is considered a “theory” and not a “hypothesis.” 3 pts,c) Provide a description of eukaryotic and prokaryotic cells, including at least 4 similarities and 4 structural differences. 4 pts,d) Describe the sequence of events with anaerobic ancestral proto-eukaryotes and aerobic prokaryotes that led to the formation of mitochondria and chloroplasts inside eukaryotic cells. (Be sure to define aerobic and anaerobic respiration.) 6 pts,e) Explain how each, the anaerobic ancestral proto-eukaryotes and aerobic prokaryotes, benefited from the relationship. 4 pts,f) Describe 7 pieces of evidence for this scientific theory. Some of this evidence will consist of a list of similarities between mitochondria characteristics and bacteria characteristics. Along with this list of similarities, explain HOW the characteristics are similar. 10 pts,g) The Endosymbiotic Theory…arrow_forwardA scientist has discovered a new species and is tasked with identifying which of the kingdoms of life the organism might fit. Multicellular with nuclei Presence of a cell wall containing chitin Heterotrophic Non-motile Question options: Fungi Protista Plantae Animalia Protists are a group of organisms that are eukaryotic. However, they are a diverse group, with some of the members of the group having a more recent common ancestor with plants while others have a more recent common ancestor with animals. Algae are protists that are more closely related to plants than any other group. Which characteristics would algae share with plants but NOT with animals? Question options: DNA Ribosomes Chloroplasts Mitochondriaarrow_forwardWhat are one of the main traits that make bacteria and archae unique in comparison to protists, fungi, amáinala and plants? - they have RNA -fungi have chitin - they are single called organismos that do not have membrane bound organelles or bucked - they diverged 3 billion years ago from each other - they have glycolysisarrow_forward
