A simple mechanical tissue devoid of lignin is:

Options

A. chlorenchyma
B. parenchyma
C. collenchyma
D. sclerenchyma

Explanation

To solve the question "A simple mechanical tissue devoid of lignin is:", we need to analyze the options provided: chlorenchyma, parenchyma, collenchyma, and sclerenchyma.

### Step-by-Step Solution:

1. **Understanding the Types of Tissues**:
- Mechanical tissues in plants provide support and structure. They can be classified into simple and complex tissues. Simple mechanical tissues include collenchyma and sclerenchyma.

2. **Analyzing Chlorenchyma**:
- Chlorenchyma is a type of parenchyma that contains chlorophyll and is involved in photosynthesis. However, it is not classified as a mechanical tissue. Therefore, chlorenchyma is not the correct answer.

3. **Analyzing Parenchyma**:
- Parenchyma is a simple tissue that is primarily involved in storage, photosynthesis, and tissue repair. It is not a mechanical tissue and does not provide structural support. Thus, parenchyma is also not the correct answer.

4. **Analyzing Collenchyma**:
- Collenchyma is a type of simple mechanical tissue that provides support, especially in young and growing parts of the plant. It is characterized by its thickened cell walls, which are primarily made of pectin and do not contain lignin. Therefore, collenchyma fits the description of a simple mechanical tissue that is devoid of lignin.

5. **Analyzing Sclerenchyma**:
- Sclerenchyma is another type of mechanical tissue, but it is characterized by having thick walls that contain lignin, which provides rigidity and strength. Therefore, sclerenchyma cannot be the correct answer.

6. **Conclusion**:
- Based on the analysis, the correct answer to the question is **collenchyma**, as it is a simple mechanical tissue that is devoid of lignin.

### Final Answer:
**Collenchyma**
