Here's why:

* Structure: The cell wall is a rigid outer layer that provides support and protection for the plant cell.

* Composition: It's mainly composed of cellulose, a complex carbohydrate, which is not considered a living component.

* Function: While the cell wall plays a vital role in the plant's survival, it doesn't carry out any of the metabolic processes that define life.
