Based on the provided text, which of the following statements accurately describes a key difference between prokaryotic and eukaryotic flagella?

  • A: Prokaryotic flagella are typically ten times wider than eukaryotic flagella.
  • B: Prokaryotic flagella are not covered by an extension of the plasma membrane, unlike eukaryotic flagella.
  • C: Both prokaryotic and eukaryotic flagella are considered homologous structures, indicating a shared evolutionary origin.
  • D: Their molecular compositions and mechanisms of propulsion are identical.

Explanation

The text explicitly states: 'Prokaryotic flagella... are not covered by an extension of the plasma membrane see Figure 6.24 .' This highlights a key structural difference compared to eukaryotic flagella.
