Answer to Question #62697 in Cell Biology for brenda
Is the structure of the cell wall related to its function? If so, how?
Cell wall is usually foormed by a network of molecules of the particular type (chitin in fungi, cellulose in plants). The long fibrillar moleucles stretching in different directions ensure the ability to resist pressure, acting in any direction. The network of moleucles of the same type can be additionally strengthened by other substances. For example, in plants lignin is used for additional strength.
