82. The fundamental difference in the structural response of a plant cell versus an animal cell to a highly hypertonic external fluid environment is that

A. The plant cell bursts while the animal cell stays stable
B. The plant cell experiences plasmolysis while keeping its outer shape, whereas the animal cell shrinks completely
✓
C. The plant cell undergoes immediate binary fission
D. The animal cell synthesizes a protective cellulose wall

📝 Explanation

The plant cell's protoplast shrinks inward while its rigid wall maintains the outer cell shape; the wall-less animal cell shrivels up completely.

📖 Additional Information

  • The plant cell bursts while the animal cell stays stable
  • The plant cell experiences plasmolysis while keeping its outer shape, whereas the animal cell shrinks completely
  • The plant cell undergoes immediate binary fission
  • The animal cell synthesizes a protective cellulose wall

The plant cell's protoplast shrinks inward while its rigid wall maintains the outer cell shape; the wall-less animal cell shrivels up completely.
