Translocation of minerals from mature leaf to young leaf occurs through mostly

Options

A. Xylem
B. Phloem
C. Parenchyma
D. Apoplast

Answer

**Step-by-Step Solution:**

1. **Understanding Translocation**: Translocation refers to the movement of substances within a plant. In this context, we are focusing on the movement of minerals from mature leaves to young leaves.

2. **Identifying the Pathway**: The primary pathway for the translocation of minerals in plants is through specialized tissues known as xylem.

3. **Role of Xylem**: Xylem is responsible for transporting water and dissolved minerals from the roots to various parts of the plant, including leaves.

4. **Mechanism of Transport**: The transport of minerals occurs along with the ascending stream of water. As water is absorbed by the roots and moves upward through the xylem, it carries dissolved mineral salts along with it.

5. **Evidence of Mineral Presence**: Experiments have shown that xylem sap contains mineral salts, confirming that xylem is indeed the pathway for the translocation of these minerals.

6. **Conclusion**: Therefore, the translocation of minerals from mature leaves to young leaves occurs predominantly through the xylem.

**Final Answer**: Translocation of minerals from mature leaf to young leaf occurs mostly through xylem.
