Chapter 4, Problem 1SQ
Most prokaryotes range in size from 0.5 to 2.0 μm, yet have large surface-to-volume ratios. This large surface-to-volume ratio allows prokaryotes to:
- (a) Ward off invaders
- (b) Resist antibiotics
- (c) Get nutrients easily to all parts of the cell
- (d) Undergo meiosis
- (e) b and d
