Question

Choose the correct answers from the alternatives given.
Bast fibres present in woody stem belong to

• A. Cork
• B. Phloem
• C. Cortex
• D. Xylem

Answer 1

The correct option is B Phloem

Bast fibres are the other name for phloem fibres. These are sclerenchymatous fibres that are elongated but do not possess branches. They have pointed needle-like apices. They provide mechanical support to the plant because of their thick cell wall. At maturity, these fibres lose their protoplasm and become dead. These fibres are generally absent in primary phloem and found only in secondary phloem. They are used in jute, flax and hemp.

Hence, the correct answer is 'Phloem'.
