21. The physiological consequence of placing a typical animal erythrocyte into a highly hypotonic distilled water solution is

A. Plasmolysis
B. Severe turgidity without rupture
C. Hemolysis (osmotic bursting)
✓
D. Immediate crenation

📝 Explanation

Lacking a rigid cell wall to resist hydrostatic pressure, animal cells absorb water via osmosis until the plasma membrane ruptures.

📖 Additional Information

  • Plasmolysis
  • Severe turgidity without rupture
  • Hemolysis (osmotic bursting)
  • Immediate crenation
