Which of the following plant tissue provide mechanical strength to plants?

Options

A. Parenchyma
B. Collenchyma
C. Sclerenchyma
D. Aerenchyma

Answer

To answer the question "Which of the following plant tissue provides mechanical strength to plants?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which plant tissue provides mechanical strength. Mechanical strength is important for the support and stability of the plant.

2. **Identify the Options**: The options provided typically include various types of plant tissues such as parenchyma, collenchyma, sclerenchyma, and possibly others.

3. **Analyze Each Option**:
- **Parenchyma**: This tissue is primarily involved in storage and photosynthesis. It does not provide mechanical strength.
- **Collenchyma**: This tissue provides flexible support, particularly in young stems and leaves. While it offers some support, it is not primarily for mechanical strength.
- **Sclerenchyma**: This tissue consists of dead cells and is responsible for providing rigid mechanical support. It is found in parts of the plant that require strength, such as the outer layers of seeds and stems.
- **Aerenchyma**: This tissue is involved in gas exchange and does not provide mechanical strength.

4. **Conclusion**: Based on the analysis, the tissue that provides mechanical strength to plants is **sclerenchyma**.

5. **Final Answer**: The correct answer is **sclerenchyma**.
