Which of the following statements is incorrect about sclereids (stone cells)

Options

A. Variously shaped
B. Highly thickened + lignified cell wall and lumen is narrow
C. Commonly found in the fruits, wall of nuts, seed coats of legumes and leaves
D. They are types of parenchyma

Answer

To determine which statement about sclereids (stone cells) is incorrect, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Sclereids (Stone Cells)**:
- Sclereids are a type of sclerenchyma cell, known for providing structural support in plants. They are characterized by their hard and thickened cell walls.

2. **Analyzing the Options**:
- **Option 1**: "Variously Shaped"
- Sclereids can indeed be found in various shapes such as spherical, oval, or cylindrical. This statement is correct.

- **Option 2**: "Highly Thickened plus Lignified Cell Wall and Lumen is Narrow"
- Sclereids have thickened and lignified cell walls, and their lumen (the interior space) is typically narrow. This statement is also correct.

- **Option 3**: "Commonly Found in the Fruits, Wall of Nuts, Seed Coat of Legumes and Leaves"
- Sclereids are commonly found in these structures, providing hardness and protection. This statement is correct as well.

- **Option 4**: "They are Types of Parenchyma"
- This statement is incorrect. Sclereids are not types of parenchyma; they are a type of sclerenchyma, which is distinct from parenchyma tissue.

3. **Conclusion**:
- The incorrect statement about sclereids is **Option 4**: "They are Types of Parenchyma."

### Final Answer:
The incorrect statement about sclereids (stone cells) is **Option 4**: "They are Types of Parenchyma."
