Differentiation in phloem is

Options

A. Sometimes centripetal
B. Sometimes centrifugal
C. Always centripetal
D. Always centrifugal

Answer

**Step-by-Step Solution:**

1. **Understanding Phloem Differentiation**:
- Phloem is a type of vascular tissue in plants responsible for the transport of nutrients, particularly sugars produced through photosynthesis.

2. **Identifying the Type of Differentiation**:
- Differentiation refers to the process by which cells become specialized in structure and function. In the context of phloem, we need to determine how these cells differentiate.

3. **Centrifugal Differentiation**:
- The key aspect of phloem differentiation is that it occurs in a centrifugal manner. This means that the differentiation starts from the center of the vascular bundle and moves outward towards the periphery.

4. **Clarifying Terms**:
- "Centrifugal" means moving away from the center, while "centripetal" means moving towards the center. In the case of phloem, the correct term is centrifugal.

5. **Conclusion**:
- Therefore, we conclude that differentiation in phloem is characterized as centrifugal differentiation, meaning it occurs away from the center of the vascular tissue.

**Final Answer**: Differentiation in phloem is centrifugal.
