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.
What else can I help you with?
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?
For plant cells, there is a cell wall outside of the cell's membrane. Animal cells do not have walls, so there is no structure outside of the cell membrane.
Does an animal cell have a cell wall?
No, animal cells do not have a cell wall.
What part of the cell is strong and stiff and hard to get through and only found in plants?
The cell wall.But it is not only found in plants, both bacteria and fungi have cell walls too.

What does a plant cell wall and animal cell wall have in common?
An animal cell does not have a cell wall.
What is cellouse cell wall?
Cell wall made out of cellulose is the cell wall of a plant. A fungi has a cell wall composed of chitin and a bacteria has a cell wall composed of glycoprotein.
What does the cell wall do in the plant cell?
