Morphology
The compound 'cell wall' is compositionally transparent: it denotes a 'wall' associated with a 'cell', so a B1 learner who knows 'cell' and 'wall' can infer a rigid layer surrounding the cell that provides structural support and protection. This formation is cross-linguistically common (e.g., French 'paroi cellulaire', Spanish 'pared celular') and follows standard noun+noun composition rather than an idiomatic shift, so it is readily predictable.
Etymology
Cell wall comes from the simple image of a wall around a cell. Like a house wall that gives shape and keeps things out, the cell wall is a hard outer layer around plants, fungi, and some bacteria, so it gives 'support' and 'protection' and helps keep the cell's shape.
