The organization of microfibrils forming the primary cell wall is rather disorganized. However, another mechanism is used in secondary cell walls leading to its organization. Essentially, lanes on the secondary cell wall are built with microtubules. These lanes force microfibrils to remain in a certain area while they wrap.
Cellulose microfibrils are unique matrix macromolecules, in that they are assembled by cellulose synthase enzymes located on the extracellular surface of the plasma membrane. [17] It is believed that the plant can “anticipate their future morphology by controlling the orientation of microfibrils” by a mechanism where cellulose microfibrils ...
It sometimes consists of three distinct layers - S 1, S 2 and S 3 - where the direction of the cellulose microfibrils differs between the layers. [1] The direction of the microfibrils is called microfibril angle (MFA). In the secondary cell wall of fibres of trees a low microfibril angle is found in the S2-layer, while S1 and S3-layers show a ...
However, the primary cell wall, can be defined as composed of cellulose microfibrils aligned at all angles. Cellulose microfibrils are produced at the plasma membrane by the cellulose synthase complex, which is proposed to be made of a hexameric rosette that contains three cellulose synthase catalytic subunits for each of the six units.

Fibrillin-1 is a major component of the microfibrils that form a sheath surrounding the amorphous elastin. It is believed that the microfibrils are composed of end-to-end polymers of fibrillin. To date, 3 forms of fibrillin have been described.
