Briefly explain how the eukaryotic cell could have evolved fromprokaryotic ones.
Serial endosymbiosis is the most supported theory on how the first eukaryotic cells evolved from prokaryotic cells. The figure depicts the evolution of eukaryotic cells which include links to prokaryotic cells from early in the history of life.
Identify the cellular structures involved in the connection of eukaryotic and prokaryotic cells. Describe the characteristics of the cellular structures that supports the evolutionary connection.
State a claim on how eukaryotic cells evolved. Using evolutionary evidence justify your claim. The cells modeled above are a result are descendants of an original cell.
Describe how the endosymbiotic theory explains eukaryotic cell evolution.
