   Mar 15, 2019 · A cell wall provides an additional layer of protection on top of the cell membrane. It is found in plants, algae, fungi, prokaryotes and eukaryotes. The cell wall makes plants rigid and less flexible. It is primarily made up of carbohydrates like pectin, cellulose and hemicellulose.

   The cell wall structure has three layers; middle lamella, primary, and secondary cell wall. Middle lamella is the outer layer of the plant cell wall. It works as an interface between neighboring cells and attaches them. The layer has pectin, lignin, and some proteins.

   Plant cells have a cell wall (made of cellulose), chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not. Green plants are capable of synthesizing glucose (C 6 H 12 O 6 ) from carbon dioxide (CO 2 ) and water (H 2 O) by using solar energy in the process known as photosynthesis.

   What is the structure and composition of the cell wall?

   • The composition and structure of the cell wall varies between species, but in general, it consists of a framework of cellulose microfibrils embedded in a matrix of other polysaccharides, proteins, and in some cases, lignin. In plant cells, the cell wall is typically composed of several layers:
