41. The structural property that renders the plant cell wall completely permeable to dissolved mineral ions and water molecules despite its rigidity is the

A. Presence of a hydrophobic lipid bilayer core
B. Porous network meshwork formed between loosely packed microfibrils
✓
C. Complete absence of polar chemical groups
D. Alignment of tight occluding junctions

📝 Explanation

The interlaced arrangement of cellulose microfibrils leaves large physical pores that allow water and small solutes to diffuse freely.
