Simple mechanical tissue devoid of lignin is represented by

Options

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

Explanation

To solve the question "Simple mechanical tissue devoid of lignin is represented by," we will analyze the options provided and determine which one meets the criteria of being a simple mechanical tissue without lignin.

### Step-by-Step Solution:

1. **Understand the Types of Tissues**:
- We need to recognize that mechanical tissues can be classified into simple and complex tissues. Simple tissues are made up of one type of cell.

2. **Identify the Options**:
- The options given are:
- A) Parenchyma
- B) Sclerenchyma
- C) Collenchyma
- D) Tracheids

3. **Analyze Each Option**:
- **Parenchyma**: This is a simple tissue that is primarily involved in functions like photosynthesis, storage, and secretion. It does not provide mechanical support.
- **Sclerenchyma**: This tissue is characterized by its lignified cell walls, which means it contains lignin and provides mechanical support.
- **Collenchyma**: This tissue has cell walls made of cellulose, hemicellulose, and pectin, and it is known for providing mechanical support, especially in young stems and leaves. Importantly, it does not contain lignin.
- **Tracheids**: These are part of the xylem and have lignified walls, primarily involved in the conduction of water and minerals.

4. **Conclusion**:
- Based on the analysis, the only simple mechanical tissue that is devoid of lignin is **C) Collenchyma**.

### Final Answer:
The simple mechanical tissue devoid of lignin is represented by **C) Collenchyma**.
