[Campbell Biology P.147] Which of the following statements accurately describes a key differ... | Practice Question

Which of the following statements accurately describes a key difference between eukaryotic and prokaryotic cells based on the provided text?

  • A: Eukaryotic cells contain regions surrounded by proteins for specific reactions, unlike prokaryotic cells.
  • B: The cytoplasm of eukaryotic cells refers to the region between the nucleus and plasma membrane, whereas prokaryotic cells lack a nucleus.
  • C: Prokaryotic cells typically have diameters between 10-100 µm, while eukaryotic cells are 0.1-1.0 µm.
  • D: Membrane-bounded organelles are a defining feature of prokaryotic cells.

Explanation

The text explicitly states that 'in eukaryotic cells, this term cytoplasm refers only to the region between the nucleus and the plasma membrane.' It also mentions that 'membrane-bounded structures are absent in almost all prokaryotic cells,' and 'Eukaryotic means "true nucleus"... prokaryotic means "before nucleus"', implying prokaryotic cells lack a true nucleus. Option B accurately captures these distinctions.
