The microfibril is a very fine fibril, or fiber-like strand, consisting of glycoproteins and cellulose. It is usually, but not always, used as a general term in describing the structure of protein fiber, examples are hair and sperm tail. Its most frequently observed structural pattern is 9+2 pattern in which two central protofibrils are surrounded...

Basic structural unit of the plant cell wall, made of cellulose in higher plants and most algae, chitin in some fungi and mannan or xylan in a few algae. Higher plant microfibrils are about 10nm in diameter and extremely long in relation to their width. The cellulose molecules are oriented parallel to the long axis of the microfibril in a paracryst...

Basic structural unit of the plant cell wall, made of cellulose in higher plants and most algae, chitin in some fungi, and mannan or xylanin a few algae. Higher plant microfibrils are about 10nm in diameter, and extremely long in relation to their width. The cellulose molecules are oriented parallel to the long axis of the microfibril in a paracrystalline array, which provides great tensile strength. The microfibrils are held in place by the wall matrix, and their orientation is closely controlled by the protoplast.
