The movement of water and minerals in xylem and the movement of phloem sap in phloem is respectively

Options

A. Unidirectional, bidirectional
B. Bidirectional, bidirectional
C. Bidirectional, unidirectional
D. Unidirectional, undirectional .

Answer

### Step-by-Step Solution:

1. **Understanding Xylem Function**:
- Xylem is responsible for the transport of water and dissolved minerals from the roots to the rest of the plant, primarily the leaves.
- The movement of water and minerals occurs in one direction, which is upward from the roots through the stem to the leaves.

2. **Understanding Phloem Function**:
- Phloem is responsible for the transport of organic nutrients, particularly sugars produced during photosynthesis.
- The movement of phloem sap can occur in multiple directions, allowing the distribution of nutrients to various parts of the plant, including roots, stems, and leaves.

3. **Direction of Movement**:
- For xylem: The movement is **unidirectional** (upward).
- For phloem: The movement is **bidirectional** (both upward and downward).

4. **Conclusion**:
- Therefore, the movement of water and minerals in xylem is unidirectional, while the movement of phloem sap in phloem is bidirectional.

5. **Final Answer**:
- The correct answer is: **Unidirectional (for xylem) and Bidirectional (for phloem)**.
