Question

of jute, hemp and flax are used to make ropes.

• A. Sieve tube elements
• B. Companion cells
• C. Phloem parenchyma
• D. Phloem fibres

Answer 1

The correct option is D Phloem fibres

Phloem in angiosperms consist of sieve tube elements, companion cells, phloem parenchyma and phloem fibres. Gymnosperms lack sieve tubes and companion cells.
Phloem fibres die when they mature. The cell wall of the fibres are very thick and they are elongated and unbranched. Phloem fibres of jute, flax and hemp are used commercially to make ropes.
