Identify three features that distinguish archaeal plasma membranes from those of bacteria.
In the diagram below, identify the structures of a cyanobacterial cell based on the following descriptions:
a) Outer cellular covering which includes:
Mucilaginous layer – outermost layer covering the cell wall; protects the cell from harmful factors of the environment
Cell wall – found just below the mucilaginous layer; 2 or 3-layered, the inner layer lies in between the outer wall layer and plasma membrane; the outer layer is made of peptidoglycan
Innermost plasma membrane – selectively permeable membrane enclosing the cytoplasm
b) Cytoplasm – found below the plasma membrane; the protoplasm which contains structures of different shapes and functions. Lamellae, which contain pigments such as chlorophylls, carotenes, xanthophylls, phycoerythrin and phycocyanin, are located in the peripheral region of cytoplasm. Ribosomes may also be found scattered in the cytoplasm.
c) Nucleic material – the nucleoplasm that is centrally located in the cell and contains chromatin in the form…

- One organism found in a termite’s gut is Mixotrichia paradoxa. This strange creature looks like a single-celled swimming ciliate under low magnification. However, the electron microscope reveals that it contains spherical bacteria rather than mitochondria and has on its surface, rather than cilia, hundreads and thousands of spirilla and bacilla bacteria. You are the scientists who first observed this organism. How would you describe this organism- single-celled? Aggregate? Colony? Multicellular? Can the structure of this organism give you any insight into the evolution of eukaryotic cells? (Hint: the endosymbiosis hypothesis)arrow_forwardDespite many interesting characteristics and features observed in Archaea, why is there not much study about these organisms?arrow_forwardAnswer the following questions: Which cell shapes are observed members of both Bacteria and Archaea? Which are unique to bacteria? Which to archaea? Both bacteria and archaea can have S-layers. How does their use as components of the cell envelope differ? What observations about cannulae and hami suggest that they allow archaeal cells to adhere surfaces, including other cells? List three aspects of archaeal flagella and flagellar motility that are like bacterial flagella and flagellar motility. INCLUDE REFERENCES!arrow_forward
- Some archaea have unique phospholipids in their cytoplasmic membrane that A) form a monolayer due to the presence of diglycerol tetraethers. B) form a bilayer due to the presence of sterols. C) form a stable ring structure due to the presence of crenarchaeol. D) form a bilayer due to the presence of phosphatidylethanolamine.arrow_forwardSome prokaryotes, especially archaea, are capable of living in extreme environments, such as deep-sea vents, where temperatures can reach 80°C (176°F). Few organisms can survive at this temperature. What adaptations might archaea possess that allow them to survive in such extreme heat?arrow_forwardArchaea exhibit a wide variety of cell shapes, including some that are unique. Suggest why this diversity exists and what advantages the unique shapes might confer.arrow_forward
