Question

question 56 (essay worth 8 points) (02.03a hc) there are two types of cells, prokaryotic and eukaryotic. although the types of cell share some similarities, compartmentalization is not a shared characteristic. a describe the endosymbiotic theory. explain the similarities and differences between the compartmentalization between prokaryotic and eukaryotic organisms. provide evidence that supports the endosymbiotic theory

Explanation:

The endosymbiotic theory posits that eukaryotic organelles like mitochondria and chloroplasts were once independent prokaryotic organisms that were engulfed by a larger cell. Similarities between prokaryotes and eukaryotes include having a cell membrane and genetic material (DNA). Differences in compartmentalization are that prokaryotes lack membrane - bound organelles while eukaryotes have them. Evidence for the endosymbiotic theory includes the presence of circular DNA in mitochondria and chloroplasts (like prokaryotic DNA), and their own ribosomes which are similar to prokaryotic ribosomes.

Answer:

The endosymbiotic theory suggests that certain organelles in eukaryotic cells originated as free - living prokaryotes. Similarities between prokaryotic and eukaryotic organisms: Both have cell membranes, cytoplasm, and genetic material (DNA). Differences in compartmentalization: Prokaryotic cells lack membrane - bound organelles, while eukaryotic cells have a nucleus and various membrane - bound organelles. Evidence for the endosymbiotic theory: Mitochondria and chloroplasts have their own circular DNA (similar to prokaryotic DNA), their own ribosomes (similar to prokaryotic ribosomes), and can replicate independently within the cell.
