Fibres/sclereids are short, broad and occur individually or in small groups.

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of Fibers and Sclereids**:
- Fibers are elongated, slender cells that provide support and are typically found in bundles.
- Sclereids, on the other hand, are short, broad cells that can be oval or spherical in shape. They have thickened cell walls.

2. **Identifying the Characteristics**:
- The question states that fibers/sclereids are short, broad, and occur individually or in small groups.
- Sclereids fit this description as they are indeed short and broad, and they can occur either singly or in small clusters.

3. **Location of Sclereids**:
- Sclereids are found in various parts of the plant, including roots, stems, flowers, leaves, and fruits. This widespread presence indicates their importance in plant structure.

4. **Conclusion**:
- Based on the characteristics and locations discussed, the correct answer to the question is that sclereids are the type of cells being described. They are short, broad, and can occur individually or in small groups.
