A Picture Of The Cell Wall. The middle lamella, shown along the top of the diagram, is a sticky layer that. A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane.
The cell wall surrounds the cell membrane and serves to strengthen and protect the cell.
Plant cell walls are made up of cellulose, hemicellulose, pectin and lignin. However, it's one of the most important components of plant cells. In addition to cellulose, other polysaccharides commonly found in the plant cell wall include hemicellulose and pectin, shown in the diagram above. Learn about the functions and chemical components of cell wall, specialized form of extracellular matrix that surrounds every cell of a plant.
