- Serial endosymbiosis is the most supported theory on how the first eukaryotic cells evolved from prokaryotic cells. The figure depicts the evolution of eukaryotic cells which include links to prokaryotic cells from early in the history of life. Identify the cellular structures involved in the connection of eukaryotic and prokaryotic cells. Describe the characteristics of the cellular structures that supports the evolutionary connection. State a claim on how eukaryotic cells evolved. Using evolutionary evidence justify your claim. The cells modeled above are a result are descendants of an original cell.arrow_forwardWhich of the following pieces of evidence could support the endosymbiotic theory if found to be true? Traces of peptidoglycan in the cytoplasm in eukaryotes Presence of rRNA in eukaryotes Presence of 80S ribosomes in eukaryotes The discovery of a unicellular eukaryotearrow_forwardDoes the following phylogenetic tree provide evidence to support or refute the endosymbiosis hypothesis?

- The answer to the question of how eukaryotic cells evolved has been suggested in the Endosymbiotic Theory. Provide at least 4 pieces of evidence to support this theory.arrow_forwardIdentify four organelles that should be present in the eukaryotic organism and describe the function of each organelle. Correctly relate 3 eukaryotic organelles to prokaryotic function. Defines endosymbiosis and describes 3 observations that support the endosymbiotic theory.arrow_forwardAfter the glacial retreat at the end of the last ice age, some three-spine stickleback fish (Gasterosteus aculeatus) were isolated in small lakes. A mutation occurred in these fish that resulted in the loss of pelvic spines. Today, all freshwater sticklebacks lack pelvic spines, but are still classified as members of the same species as marine sticklebacks. Scientists collected sticklebacks from both marine and freshwater environments and placed them together in a controlled environment. Which of the following statements describes the effect of the mutation on their ability to interbreed? They should be able to interbreed and produce fertile offspring. They will not be able to interbreed and produce offspring because of hybrid breakdown. They will not be able to interbreed and produce offspring because of mechanical isolation. They should be able to interbreed and produce offspring, but the offspring may experience reduced hybrid fertility.arrow_forward
- Evolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane. Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms? A - the development of genetic transfer mechanisms in prokaryotes B - the evolution of predatory or parasitic relationships in prokaryotes C - the emergence of collections of cells functioning together in prokaryotes D = the expansion of internal structures to support larger individual cells in prokaryotesarrow_forwardUnder the endosymbiotic theory for the origin of the eukaryotic cell. The ancestor of mitochondria and chloroplasts original became part of mutualism with a larger host cell. Which of the following best explains this mutualism? A) The mitochondria and chloroplasts provided specialized reproduction as part of the proto-germ line while the larger host cell provided energy for growth and reproduction. B) The mitochondria and chloroplasts provided gene products that could be used by the larger host cell for improved parasitization. C) The mitochondria and chloroplasts provided molecular energy in return for protection by the larger host cell. D) The mitochondria and chloroplasts produce toxins that the larger cell utilized to defend itself from other cells mutually increasing the defense of all those involved.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?
