What is the typical diameter range of prokaryotic cells?
What is the typical diameter range of prokaryotic cells?
- 0.5 to 15.0 μm
- 1.0 to 10.0 μm
- 0.1 to 5.0 μm (correct)
- 10 to 100 μm
How does the size of prokaryotic cells affect the diffusion of molecules within them?
How does the size of prokaryotic cells affect the diffusion of molecules within them?
- Diffusion is enhanced by larger surface areas only.
- Waste products remain inside the cell longer due to size.
- Smaller size reduces the rate of diffusion.
- Ions and organic molecules can quickly diffuse within the cell. (correct)

Study Notes
Size Comparison
- Prokaryotic cells range from 0.1 to 5.0 μm in diameter.
- Eukaryotic cells are larger, with diameters between 10 to 100 μm.
Diffusion Efficiency
- The small size of prokaryotes facilitates rapid diffusion of ions and organic molecules within the cell.
- Wastes produced in prokaryotic cells can also diffuse quickly, promoting efficient cellular function.
Structural Adaptations in Eukaryotes
- Eukaryotic cells require adaptations to enhance intracellular transport due to their larger size.
- These adaptations contrast with the diffusion capabilities seen in prokaryotic cells.
