Explain what happens to plant and animal cells when placed in hypertonic, hypotonic, and isotonic environments.
What will be an ideal response?
Plant cells will become turgid in hypotonic environments while animal cells will lyse due to lack of a cell wall. Plant cells will wilt in an isotonic environment and animal cells are fine in this isotonic environment. In hypertonic solutions, plant cells plasmolyze and lose water and animal cells crenate or shrink as well.
