Final answer:

False. Intermediate filaments do not have polarity with a plus end and a minus end. They are composed of long fibrous subunits of proteins like keratin and are important for maintaining cell shape and structure.

Step-by-step explanation:

False. Each intermediate filament does not have polarity with a plus end and a minus end. Unlike microtubules and actin filaments, intermediate filaments do not have 'plus' and 'minus' ends. Monomers of intermediate filaments are non-polar, and they do not show directionality or polarity like microfilaments. Intermediate filaments are composed of long fibrous subunits of proteins like keratin and are important for maintaining cell shape and structure.
