According to the endosymbiotic theory, mitochondria and chloroplasts evolved from aerobic and photosynthetic bacteria that were engulfed and "took up" residence in a host prokaryotic cell. Use your knowledge of how plant and animal cells differ to answer the following questions:A. Did the ancestral plant cell engulf both types of bacteria? Cite evidence to justify your answer.B. Did the ancestral animal cell engulf both types of bacteria? Cite evidence to justify your answer.C. If the answer to either A or B is yes, then which type of bacteria would have been engulfed first? Cite evidence to justify your answer.
What will be an ideal response?
A. Yes, the ancestral plant cell engulfed both types of bacteria. Plant cells contain both mitochondria and chloroplasts.
B. No, the ancestral animal cell engulfed only the aerobic bacterium. Animal cells have mitochondria but no chloroplasts.
C. The ancestral cell first engulfed an aerobic bacterium, then diverged into two cell lines, each having the evolving mitochondria. One line evolved into an animal cell, which only has mitochondria and not chloroplasts. The other cell then engulfed the photosynthetic bacteria and through time became plant cells, which contain mitochondria and chloroplasts.
