Step by step
Solved in 2 steps
- What evidence supports the hypothesis that mitochondriapreceded plastids in the evolution of eukaryotic cells?What is the endosymbiotic hypothesis about the origin of mitochondria? What are the molecular facts that support the hypothesis? To which other cellular organelles can the hypothesis also be applied?Name three facts that show that mitochondria have bacterial origins.
- A scientist discovered a new group of unicellular organisms that lack mitochondria but possess an organelle related to the endoplasmic reticulum and is involved in energy production. The scientist hypothesizes that this organelle might be a missing link in the evolution of mitochondria. A) Do you agree with this hypothesis? Explain. B) Based on the available evidence, what is the most likely hypothesis for the origin of mitochondria? Provide four pieces of evidence to support this theory and justify why they are valid.Describe the features of mitochondria and chloroplasts that support the endosymbiotic theory.Why do scientist believe that mitochondria originated from ancient prokaryotes?
- In the late 1960s (and since), Lynn Margulis (and others) provided considerable evidence for the endosymbiotic theory of the origin of various organelles in eukaryotic cells.What is the endosymbiotic theory? Which two eukaryotic organelles were proposed to have arisen as endosymbionts? What evidence did Margulis present to support each organelle as an endosymbiont?The endosymbiotic theory pertains to which organelle within eukaryotes because of the presence of 70S ribosomes, circular DNA, and the replication of this organelle independent from mitosis? O 1) nucleus O 2) lysosomes. O 3) golgi 4) endoplasmic reticulum 5: O 5) mitochondriaBased on the presence of mitochondria and chloroplast within eukaryotic cells, what organelle do you think originated within eukaryotic cells first: mitochondria or chloroplast? Why?
- Why does mitochondria and chloroplast are considered as ancestors of representative eukaryotic cells, particularly plant and animal cell?If mitochondria originated as proteobacteria and chloroplasts are descended from cyanobacteria, where does the rest of the eukaryotic cell come from?In the evolution of the eukaryotic cell, these cells have evolved key changes that include which of the following: a) These cells reproduce by copying their DNA perfectly each generation b) They have their DNA in the nucleoid area c) They have adapted the mesosome membrane system of the prokaryote to form a nucleus and an endoplasmic reticulum d) each new type of new eukaryote cell has its mRNA unchanged from its original mRNA e) none of these are true
