The phloem formed from vascular cambium is known as

Options

A. primary phloem
B. secondary phloem
C. protophloem
D. metaphloem

Answer

To answer the question "The phloem formed from vascular cambium is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plant Tissues**:
- Plants have various types of tissues, including meristematic tissues (which are responsible for growth) and permanent tissues (which perform specific functions).

2. **Identifying Vascular Tissues**:
- Among the permanent tissues, vascular tissues are crucial for the transport of water, nutrients, and food. The two main types of vascular tissues are xylem and phloem.

3. **Role of Vascular Cambium**:
- Vascular cambium is a type of lateral meristem that is responsible for secondary growth in plants. It produces new vascular tissues.

4. **Formation of Secondary Tissues**:
- The vascular cambium differentiates into two types of secondary vascular tissues:
- **Secondary Xylem**: Formed towards the inner side of the cambium.
- **Secondary Phloem**: Formed towards the outer side of the cambium.

5. **Conclusion**:
- Therefore, the phloem that is formed from the vascular cambium is specifically referred to as **secondary phloem**.

### Final Answer:
The phloem formed from vascular cambium is known as **secondary phloem**.
