Jute, Flax, Hemp fibres are morphologically

Options

A. Pericyclic fibres
B. Xylem fibres
C. Phloem fibres
D. Medullary fibres

Answer

### Step-by-Step Solution:

1. **Identify the Fibers**: The question asks about jute, flax, and hemp fibers. These are all known for their use in textiles and are derived from plants.

2. **Understand Fiber Composition**: These fibers are classified as "bast fibers." Bast fibers are derived from the phloem (the part of the plant responsible for transporting nutrients) of dicotyledonous plants.

3. **Recognize Plant Origin**: Jute is obtained from plants in the genus *Corchorus*, while flax comes from *Linum usitatissimum*, and hemp is derived from *Cannabis sativa*. All these plants are dicots.

4. **Determine Morphological Classification**: Since jute, flax, and hemp fibers are derived from the phloem tissue of these dicot plants, they are classified as phloem fibers.

5. **Eliminate Incorrect Options**:
- Pericyclic fibers are found in the pericycle, which is not relevant here.
- Xylem fibers are associated with water transport and are not the source of these fibers.
- Medullary fibers are found in the pith and do not pertain to jute, flax, or hemp.

6. **Conclude the Answer**: Based on the above analysis, the correct classification for jute, flax, and hemp fibers is phloem fibers.

### Final Answer:
Jute, flax, and hemp fibers are morphologically **phloem fibers**.
