Why might vascular plants have developed relationships with so many types of microorganisms? These molecular-level interactions show many similarities when microbe-plant and microbe-human interactions are considered. What does this suggest concerning possible common evolutionary relationships?
To determine: The possible reason for the development of relationships with many types of microorganisms by the vascular plants.
Introduction: Aquatic plants have evolved into terrestrial organisms with the help of soil microorganisms. This establishes a plant-microbe relationship. The interaction between plants and microbes may be beneficial for both or for only the microbes.
Explanation of Solution
Vascular plants are the plants that can absorb water through roots and then supply it to their different parts. Vascular plants have developed a relationship with different types of microorganisms as a means of survival. This association of plants with different types of microbes ensures that if one species of microbes perishes, the other microbial species is available to increase the uptake of nutrients and water by the plant.
To determine: The common evolutionary relationships suggested by the similarities in molecular level interactions in microbe-plant and microbe-human interactions.
Introduction: Aquatic plants have evolved into terrestrial organisms with the help of soil microorganisms. This establishes a plant-microbe relationship. The interaction between plants and microbes may be beneficial for both or for only the microbes.
Explanation of Solution
The molecular level plant-microbe and human-microbe interactions show some similarities. This similarity suggests a convergent evolution of these microbes, which means that different microbial species evolved from different ancestors, but they still shared common traits due to similar selection pressures.

- What is the relationship between the sickle cell mutation and the Plasmodium parasite? Would having the HbSA genotype still be advantageous in a region where such parasites are not common? Why or why not?arrow_forwardThe endosymbiotic hypothesis for the origin of chloroplasts from gram-negative prokaryotes is supported by all of the following lines of evidence except: the presence of enzymes for the light-dependent and the dark reactions of photosynthesis the presence of circular DNA resembling that of photosynthetic eubacteria the presence of mRNA, tRNA, and rRNA similar to that of the cyanobacteria their use of mitosis rather than binary fission during cell division the presence of 70s ribosomes, consisting of 30s and 50s ribosomal subunitsarrow_forwardVolvox carteri, an volvocine alga, has approximately 2000 somatic cells and only 16 reproductive or germ line cells. The observation that multicellular individuals, like Volvox, have a much smaller subset of germ line cells compared to somatic cells appears to be general rule. Which of the following is the best evolutionary explanation for why this is the case? A) Organisms can biologically only contain a small number of germ line cells as they are always larger than somatic cells. B) Multicellular individuals with a germ line vs. somatic cell line differentiation only evolved a single time, thus all members of this lineage share the same scheme of more soma cells with a much smaller subset of germ line cells. C) Having a smaller subset of reproductive cells helps reduce the likelihood of cheating from evolving, which in turns prevents the collapse of the multicellular individual system. D) None of the above.arrow_forward
- Research an interesting example of mutualism, and present your findings in a post. The goal here is to provide examples beyond what is presented in lecture and/or your textbook. These can be animal-animal, animal-fungal, plant-fungal, plant-animal, bacteria-animal....the sky is the limit! For this particular forum, you'll be able to see other classmates postings even before you post your own. This is so you can present an example that's different from what's already been discussed. Remember that mutualistic interactions are associations that benefit both parties -- so your response should clearly indicate the role each partner plays. Let us know where these organisms are found, what kind of habitat they live in, and any other interesting , pertinent information. Also, please comment on how natural selection likely played a role in the development of your example. You can use your imagination a bit here -- I'd just like to see you connect the ideas. Your posting must be at least…arrow_forwardWhich of these is an example of inductive reasoning? A) Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic. B) These organisms live in sunny regions. Therefore, they are using photosynthesis. C) If protists are all single-celled, then they are incapable of aggregating. D) If two species are members of the same genus, they are more alike than each of them could be to a different genus.arrow_forwarda) Describe some characteristics and differences between prokaryotic and eukaryotic cells.b) How do the three domains of life differ from one another?c) Two of the organelles in eukaryotes, the mitochondrion and the chloroplast are believed to haveoriginated through a process of symbiosis.

- Evidence indicating the chloroplasts were originally free-living prokaryotes that subsequently evolved a symbiotic relationship with a eukaryotic host includes all of the following except: Ability of chloroplasts to synthesize all their own proteins Presence of circular DNA in chloroplasts and in free-living prokaryotes Similarities of rRNA sequences between chloroplasts and free-living prokaryotes Similarities of structures between chloroplasts and some contemporary free-living prokaryotes Carrow_forwardBacteria that live in the digestive systems of cows help break down the plants that cows eat, providing nutrients to cows. The digestive systems of cows offer a safe environment in which the bacteria can live and reproduce. Which type of realationship exist between the bacteria and the cows?arrow_forwardRecent evidence suggests that symbionts may be pivotal in evolutionary events. How might bacteria be involved with reproductive isolation and with the origins of multicellular animals?arrow_forward
- All of the following statements are true about the3-domain classification system EXCEPT:(a) The three domains are Bacteria, Archaea, and Eukarya.(b) Lateral gene transfer has forced us to rethink our do-main model from a “tree of life” to a “shrub of life.”(c) Domains are higher than the category of kingdoms.(d) Compared to Bacteria, Archaea inhabit the same en-virons and have the same amount of peptidoglycan intheir cell walls.(e) All of the above are true.arrow_forwardLuiz Roesch and colleagues conducted a study to determine how many types of bacteria exist in a gram of soil at different locations around the world. They found that soil from agricultural fields harbored considerably fewer species of bacteria than did soil from forests (see Life in a Bacterial World). Propose some possible reasons that agricultural fields might have less bacterial diversity than forests.arrow_forwardIn the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.arrow_forward
