Explanation
The outermost layer in a typical plant cell would be primary cell wall. It is a rigid layer that provides support and protection to the cell. It is made up of cellulose, hemicellulose, and pectin. The primary cell wall is usually thin and flexible, but it can become thicker and more rigid in some cells.
