Per NCERT, why does a PLANT cell placed in a concentrated sugar solution NOT visibly shrink (its outer boundary stays the same) — while an animal cell does shrink?
APlant cells reject all osmosis
BThe rigid cell wall maintains the plant cell's shape; the membrane pulls away from the wall but the wall itself stays intact
CPlant cells contain no water
DPlant cells absorb sugar molecules through their wall
Answer & Solution
Correct answer: B. The rigid cell wall maintains the plant cell's shape; the membrane pulls away from the wall but the wall itself stays intact
Per NCERT §2.2.2, the cell wall holds the plant cell's outer shape even as the membrane pulls away (plasmolysis). Animal cells lack a wall so they shrink directly.
