Two students are reading an article about the evidence of the endosymbiotic theory. As they are reading, they have drawn images of what they believe to be occurring on index cards. The two students are engaging in a discussion on how the index cards should be ordered to accurately show the evolution of eukaryotic cells.
Student A claims the order should be B, E, D, A, C. Their reasoning is that since the small circles without lines in the index cards represent chloroplasts, photosynthesizing organisms evolved before aerobic organisms.
Student B claims the order should be B, A, C, E, D. Their reasoning is that since the small ovals with lines in the index cards represent mitochondria, respiratory organisms evolved before photosynthesizing organisms
Use the diagram to answer the question. Which statement below is accurate about the discussion above?
student A has a correct ordering of index cards but incorrect reasoning.
student B has a correct ordering of index cards and correct reasoning.
Student A has a correct ordering of index cards and correct reasoning.
Student B has a correct ordering of index cards but incorrect reasoning.
_____ and _____ are organelles that arose from endosymbiosis
nucleus and cell membrane
mitochondria and chloroplasts
cell wall and chloroplasts
mitochondria and nucleus
Which of the following is evidence to support the endosymbiotic theory?
Mitochondria and chloroplasts have their own DNA, which is similar to prokaryotic DNA.
Fossil evidence shows that the first forms of life were prokaryotic cells.
All eukaryotic cells have a double-layered membrane composed of phosplipids and proteins.
Prokaryotes have the same number and types of enzymes as eukaryotes.
