Symbiosis has had a role in eukaryotic development?
Step by step
Solved in 2 steps
- Under 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.Mitochondria are a symbiont that most likely evolved from ?According to the endosymbiotic theory, protoeukaryotes did not have ribosomes until the endosymbiosis with mitochondria was established.
- What is one argument against the idea that the nucleus has also become part of a eukaryotic cell via an endosymbiosis event?How did endosymbiosis contribute to the evolution of eukaryotes?Discuss the Endosymbiotic Theory. Do you think it is a strong explanation on how the eukaryotes emerged on Earth?
