How does the cell wall protect a plant cell? The cell wall is thick and fibrous and provides a barrier between the cell and its external environment. The cell wall does not protect the cell because the cell membrane does. The cell wall is thin and flexible, which allows the cell to be moved without harming the organelles. The cell wall is on the inside of the cell and serves to contain the contents of the cell.

The cell wall is thick and fibrous and provides a barrier between the cell and its external environment.

Explanation:

Cell wall is a structural feature found in specific organisms like plants, bacteria, algae and some fungi. In plants, cell wall is found to coat the cell membrane, hence, providing additional support to the plant cell. The major constituent of the plant cell wall is Cellulose, which confers its rigidity upon it.

The cell wall, due to its rigid nature, protects the contents of the plant cell. Hence, it serves as a barrier between the cell and Its external environment. This means that it helps regulate what goes into the cell e.g pathogens.
