Detailed explanation-1: -A cell wall is a rigid, semi-permeable protective layer in most of the plant cells. They are made out of non-living cellulose.

Detailed explanation-2: -The cell wall is the non-living and outermost covering of a cell consisting of cellulose and is permeable.

Detailed explanation-3: -The cell wall is the non-living covering of a plant cell.

Detailed explanation-4: -The cell wall is the non-living structure of the cell made up pf cellulose in plant cells. It is very tough, a rigid layer that surrounds some types of cells. It surrounds the cell membrane and provides these cells with structural support and protection.

Detailed explanation-5: -Complete answer: In a plant cell, the cell wall is the only part that is non-living because it is an extracellular product and exists outside the living boundary of the cell i.e. the plasma membrane and protects the cell besides providing it a definite shape.
