The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membreance and provides these cells with structural support and protection, and also acts as a filtering mechanism. A major function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. They are found in plants, bacteria, fungi, algae, and some archaea. Animals and protozoa do not have cell walls.
The materials in a cell wall vary between species, and in plants and fungi also differ between cell types and developmental stages. In plants, the strongest component of the complex cell wall is a carbohydrate called cellulose, which is a polymer of glucose. In bacteria, peptidoglycan forms the cell wall. Archaean cell walls have various compositions, and may be formed of glycoprotein S-layers, pseudopeptidoglycan, or polysaccharides. Fungi possess cell walls made of the glucosamine polymer chitin, and algae typically possess walls made of glycoproteins and polysaccharides. Unusually, diatoms have a cell wall composed of silicic acid. Often, other accessory molecules are found anchored to the cell wall.
The cell wall provides structural support and shape to plant cells, helps to regulate cell growth and prevents cells from bursting due to osmotic pressure. It also acts as a barrier to protect the cell from pathogens and external stresses. Additionally, the cell wall allows for communication and adhesion between neighboring cells.
A cell wall is only found in plant cells. It is a rigid structure that gives support to a cell.

What is a outer supportive structure of a plant cell?
The cell wall is the outer supportive structure of a plant cell. It provides rigidity and support to the cell, helping the plant maintain its shape and structure. The cell wall is made up of cellulose, a complex carbohydrate that gives strength to the cell.
What structure is outside the cell membrane?
The cell wall is the structure outside the cell membrane in plant cells, fungi, and some bacteria. It provides structural support and protection to the cell.
What part of the cell is strong and stiff and hard to get through and only found in plants?
The strong and stiff outer layer found in plants is called the cell wall. It provides structural support and protection to plant cells, helping maintain their shape and rigidity.
