Peptidoglycan is a chemical compound found in the cell walls of (a) most viroids (b) most archaea (c) all prokaryotes (d) most bacteria (e) most eukarya

Expert Solution & Answer

Summary Introduction

Introduction: Bacteria and archaea are considered as prokaryotes in terms of lacking membrane-bound organelles, internal membranous structures, and cytoskeleton.

Answer to Problem 1TYU

Correct answer: Peptidoglycan is a chemical compound present in the cell walls of most bacteria. Hence, the correct answer is option (d).

Explanation of Solution

Reason for the correct answer:

The structures that are found in bacteria are the capsule, outer membrane, cell wall, plasma membrane, pilus, microcompartments, plasmid, endospores, and flagellum. The cell wall of most bacteria is made up of peptidoglycan layer. In Gram-positive bacteria, the cell wall is primarily composed of a thick layer of peptidoglycan. Gram-negative bacteria are surrounded by two membranes: outer thick membrane is made up of lipopolysaccharides and thin peptidoglycan layer.

Option (d) is given as “most bacteria”.

Bacterial cell wall is primarily composed of peptidoglycan. Hence, the correct answer is option (d).

Reason for incorrect answers:

Option (a) is given as, “most viroids”.

Viroids are the smallest infectious entities without a protein coat and cell wall. Hence, option (a) is incorrect.

Option (b) is given as, “most archaea”.

The cell wall of archaea lacks peptidoglycan. Instead it is composed of proteins and polysaccharides. Hence, option (b) is incorrect.

Option (c) is given as, “all prokaryotes”.

Archaea and bacteria are included under prokaryotes and as archaea lacks peptidoglycan in their cell walls. Thus, the statement “all prokaryotes have peptidoglycan in their cell walls” is not correct. Hence, option (c) is incorrect.

Option (e) is given as, “most eukarya”.

Peptidoglycan is not the component of cell walls of eukarya. Eukaryotic cell walls are composed of polysaccharide such as in plants (cellulose) and fungi (chitin). Hence, option (e) is incorrect.

Hence, the options (a), (b), (c), and (e) are incorrect.

Conclusion

Peptidoglycan is a component of most of the bacterial cell wall.

6. The mammalian phylogenies (labeled a and b) were produced by two different research groups. a. In which tree do phylogenetic relationships most closely align with biogeography and why? (consult the Teeling and Hedges paper) b. What are the most closely related species to Chiroptera in each tree? Might the use of convergent traits for building phylogenies explain this difference? If so, which tree is most likely to have relied on convergent traits and why? c. What are some possible reasons that the two research groups came up with different phylogenies (in general terms)? describe at least three possible reasons.

Build a model of a prokaryotic cell using any material of your choice. In your model be sure to include all the structures appropriate to your cell. You may model a bacterial cell or an archaea. You will model at least 4 structures in any model. Next, build a model of a virus using the same type of materials. You may choose any type of virus but be sure you can illustrate the key features of a virus (head shape for example). Once complete, take multiple photographs of your models from all angles. Include these images in a document that also contains the following completed table format. You may need to add rows to your table depending on the type of prokaryote you model.
