However, they also contain other components in varying amounts, including:

* Hemicellulose: Another type of carbohydrate, which acts as a glue to bind cellulose fibers together.

* Pectin: A gel-like substance that helps maintain the cell wall's structure and flexibility.

* Lignin: A rigid polymer that provides strength and support, especially in woody tissues.

* Proteins: Involved in various functions, including structural support and enzymatic activities.

The exact composition of a plant cell wall can vary depending on the plant species, tissue type, and developmental stage.
