All of the following serve an important role in determining or maintaining the structure of plant cells. which of the following are distinct from the others in their composition?
a) microtubules
b) microfilaments
c) plant cell walls
d) intermediate filaments
e) nuclear lamina

Plant cell wall

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 matrix. 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.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
