Answer:
<em>Plant cell wall</em>
Explanation:
Microtubules: These are hollow cylinders constituted by a protein called tubulin. They are important components of the cytoskeleton providing support and transport mediums to the cell.
Microfilaments: one of the fundamental components of the cytoskeleton, they are composed of filaments of the actin protein. Microfilaments are abundant in the region adjacent to the membrane, where they associate with other proteins to compose the cytoskeleton.
Cell wall: composed of polysaccharides and glycoproteins organized in a tridimensional <u>matrix</u>. The most important component is cellulose, composed of repeated glucose units joined between them. Each cellulose molecule contains about 500 glucose units.
Intermediate filaments: Insoluble, cytosolic, fibrous proteins that are present in every eukaryotic cell. They compose the cytoskeleton that supports the cellular structure and are involved in different metabolic and physiological processes. They participate in internal organelles organization.
Nuclear lamina: intercrossed net of intermediate filaments composed by lamins proteins. It is located in the nucleoplasm periphery in contact with the inner face of the nuclear cover.
