Bidirection translocation of minerals takes place in

Options

A. xylem
B. phloem
C. cambium
D. parenchyma

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the bidirectional translocation of minerals in plants. This means we need to identify which plant tissue is responsible for transporting substances in both directions.

2. **Identifying Plant Tissues**: In plants, there are two main types of vascular tissues involved in transport: xylem and phloem.

3. **Analyzing Xylem**: The xylem is primarily responsible for the transport of water and minerals from the roots to the aerial parts of the plant (leaves and stems). This movement is unidirectional, meaning it only goes in one direction (upwards).

4. **Analyzing Phloem**: The phloem, on the other hand, is responsible for transporting food (mainly sucrose) produced during photosynthesis from the leaves to other parts of the plant, including both the stem and the roots. This movement is bidirectional, meaning it can go both upwards and downwards.

5. **Considering Other Options**: Cambium is involved in secondary growth and does not play a role in the transport of minerals or nutrients. Parenchyma is a type of simple tissue that performs various functions but is not primarily involved in the transport of minerals.

6. **Conclusion**: Based on the analysis, the tissue responsible for bidirectional translocation of minerals in plants is the phloem.

**Final Answer**: The bidirectional translocation of minerals takes place in the phloem.
