The direction of movement in the phloem is (A)____ while in the xylem movement is always (B)_____

Answer

**Step-by-Step Solution:**

1. **Understanding Phloem and Xylem Functions:**
- Phloem is responsible for transporting nutrients, primarily sugars (like sucrose) and amino acids, throughout the plant.
- Xylem is responsible for transporting water and minerals from the roots to the rest of the plant.

2. **Direction of Movement in Phloem:**
- The movement of substances in the phloem is bidirectional, meaning it can flow in both directions (upwards and downwards). This allows the plant to distribute nutrients to various parts where they are needed.

3. **Direction of Movement in Xylem:**
- The movement of water and minerals in the xylem is unidirectional, which means it only flows in one direction—from the roots upwards to the leaves and other parts of the plant.

4. **Filling in the Blanks:**
- For blank (A), since the movement in the phloem is bidirectional, we write "bidirectional."
- For blank (B), since the movement in the xylem is unidirectional, we write "unidirectional."

5. **Final Answer:**
- The direction of movement in the phloem is (A) **bidirectional** while in the xylem movement is always (B) **unidirectional**.
