Prokaryotes rely on which process to take in materials and to remove wastes?
AActive pumping by organelles
BDiffusion across short distances
CTransport along microtubules
DVesicle budding from the Golgi
Answer & Solution
Correct answer: B. Diffusion across short distances
1. A prokaryote is small, from 0.1 to 5.0 micrometers across.
2. Over that short distance, ions and organic molecules entering the cell diffuse quickly to every other part.
3. Wastes produced inside can equally diffuse out again without special machinery.
4. Microtubule tracks and Golgi vesicles are eukaryotic structural adaptations, so a prokaryote cannot use them.
5. Prokaryotes depend on diffusion.
