What primary physical characteristic distinguishes protein fibers like wool and silk from cellulosic fibers like cotton?

Protein fibers decompose under high heat without burning, whereas cellulosic fibers melt. Protein fibers originate from animal sources and dissolve in dilute alkali solutions, whereas cellulosic fibers come from plants and resist dilute alkalis. Protein fibers are completely non-absorbent and dry instantly, unlike cellulosic fibers. Protein fibers cannot be dyed using conventional dyestuffs.

Correct Answer:

Protein fibers originate from animal sources and dissolve in dilute alkali solutions, whereas cellulosic fibers come from plants and resist dilute alkalis.
