A plant fibre is extracted from long stems after they are soaked so that binding substances break down. Which fibre and process are most likely involved?

Answer: A. Jute, retting

The Fibre: Jute is a bast fibre obtained from the phloem or outer stem of the plant. • The Process: Retting is the micro-biological process of soaking the long stems in water. This breaks down the cellular tissues and pectin (the natural binding substances) surrounding the tough fibres, allowing them to be easily separated from the woody core.
