AThe soft cell nuclei
BThe watery cytosol
CThe rigid cell walls
DThe plasma membranes
Answer & Solution
Correct answer: C. The rigid cell walls
1. Plant cells are wrapped in a rigid covering that sits outside the plasma membrane.
2. The crunch of raw celery is the sound of teeth tearing the rigid cell walls of the celery cells.
3. Membranes and cytosol are soft and would not produce a crunch on their own.
