Question

The commercial jute fibres are obtained from
A. Interxylary fibres
B. Xylem fibres
C. Phloem fibres
D. None of the above

Answer 1

Hint: Jute is a rough fibre which is used for as gunny bags, curtains, bags, etc. it is obtained from the Corchorus capsularis which belongs to the family Tiliaceae, they are separated from the secondary phloem of the plant.

Complete answer:The fibres are grouped into two the xylary fibres which are also called as the wood fibres they are the longest element in the xylem, the extra xylem fibres are classified as the phloem fibres, cortical fibres, and the perivascular fibres, these fibres are lignified and non- lignified.
Based on the elasticity of the fibres the body of the plant enables it to withstand the various strains. The commercial fibres which are the jute, ramie, flax are all extra xylary fibres.

Additional information: Cultivation is dependent on the climate, season, and soil type. Almost 85% of the world's jute cultivation is concentrated in the Ganges Delta.
This fertile geographic region is occupied by both Bangladesh and India (mainly West Bengal). China is also becoming a dominating place in jute cultivation.

Hence, the correct option is ‘C’

Note: Jute fibres mainly compose of the cellulose and lignin.
They are under the category of bast fibres which are collected from the skin of the plant or the secondary phloem.
