Metabolical mechanical tissue is

Options

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

Answer

To answer the question "Metabolical mechanical tissue is," we need to analyze the options provided and determine which type of tissue fits the description of being both metabolic and mechanical.

### Step-by-Step Solution:

1. **Understand the Terms**:
- "Metabolical" refers to tissues involved in metabolic processes (e.g., photosynthesis, storage).
- "Mechanical" refers to tissues that provide structural support to the plant.

2. **Identify the Options**:
- The options given are:
- Chlorenchyma
- Sclerenchyma
- Parenchyma
- Collenchyma

3. **Analyze Each Option**:
- **Sclerenchyma**: This is primarily a mechanical tissue, providing strength and support. It does not have significant metabolic functions. Therefore, it is not the correct answer.
- **Parenchyma**: This tissue is involved in storage and metabolic functions, but it does not provide significant mechanical support. Thus, it does not fit the definition of "metabolical mechanical tissue."
- **Collenchyma**: This tissue provides flexible support and is involved in growth. It has some metabolic functions, making it a candidate for being a metabolical mechanical tissue.
- **Chlorenchyma**: This is a type of parenchyma that contains chloroplasts and is involved in photosynthesis. While it is metabolic, it does not provide mechanical support like collenchyma.

4. **Conclusion**:
- The only tissue that is both metabolically active and provides mechanical support is **Collenchyma**. Therefore, the correct answer is **Collenchyma**.

### Final Answer:
Metabolical mechanical tissue is **Collenchyma**.
