Simple tissue that is not formed from vascular cambium is

Options

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

Answer

To solve the question "Simple tissue that is not formed from vascular cambium is," we will analyze the options provided and determine which one fits the criteria.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Simple Tissues**: These are tissues composed of a single type of cell. They include parenchyma, collenchyma, and sclerenchyma.
- **Vascular Cambium**: This is a type of meristematic tissue that produces secondary xylem and phloem in plants.

2. **Analyzing the Options**:
- **Option A: Collenchyma**:
- Collenchyma is a simple tissue that provides support and flexibility to young stems and leaves. It is not formed from the vascular cambium.
- **Option B: Sclerenchyma**:
- Sclerenchyma is a simple tissue that provides mechanical support and is made up of dead cells. It is typically formed from the vascular cambium.
- **Option C: Parenchyma**:
- Parenchyma is a simple tissue that is involved in storage, photosynthesis, and tissue repair. It is also formed from the vascular cambium.
- **Option D: Meristem**:
- Meristematic tissues are actively dividing cells and are formed from the vascular cambium.

3. **Identifying the Correct Answer**:
- From the analysis, collenchyma is the only tissue listed that is not formed from the vascular cambium. Sclerenchyma and parenchyma are both derived from it, and meristematic tissues are also formed from the vascular cambium.

4. **Conclusion**:
- Therefore, the correct answer to the question is **Collenchyma**.
