Answer:
C. The cells in these two areas have different functions.
Explanation:
The plant tissues are classified into three major systems: vascular, epidermic, and root systems. The vascular system is formed by tissues referred to as xylem and phloem. The epidermis is composed of superficial tissues that cover plant organs (i.e., leaves, stem, roots, etc). Finally, the root system is formed by tissues whose function is to supply to other plant tissues and store nutrients. Moreover, the plant tissues are also classified into meristematic and permanent tissues. In this case, it is reasonable to suppose that structurally different plant cells that are located at different areas of the plant will have distinct functions.
Answer: The correct option is E ( Intermediate filaments are unpolarized).
Explanation:
Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.
Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments
The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments
Some molecules are too big they cannot diffuse through the membrane, for example starch (glucose) molecules.
