Question

Quizplus · Accepted Answer

Prokaryotic flagella do not have an internal 9+2 pattern of microtubules (A) like eukaryotic flagella. They also do not have an external covering provided by the plasma membrane (B) or a basal body that is similar in structure to the cell's centrioles (D). Instead, the flagellum in prokaryotes is driven by a complex "motor" embedded in the cell wall and plasma membrane (C). Additionally, prokaryotic flagella are not enclosed in a membrane-enclosed organelle (E) like eukaryotic flagella.
