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. We need to identify which plant tissue is responsible for this process.

2. **Identifying Plant Tissues:** The main plant tissues involved in the translocation of substances are xylem and phloem. Xylem is primarily responsible for the movement of water and minerals, while phloem is responsible for the transport of food.

3. **Analyzing Xylem Function:** Xylem translocates water and minerals from the roots to the leaves. This movement is unidirectional, meaning it only goes in one direction (upward).

4. **Analyzing Phloem Function:** Phloem, on the other hand, transports food (sugars and other organic compounds) from the leaves to various parts of the plant, including the roots. This process can occur in both upward and downward directions, making it bidirectional.

5. **Considering Other Options:** The other options provided are cambium and parenchyma. Cambium is a layer of tissue responsible for growth and does not play a role in translocation. Parenchyma is a type of plant tissue involved in storage and photosynthesis, but it does not directly participate in the translocation of minerals or food.

6. **Conclusion:** Since phloem is the only tissue that allows for bidirectional translocation of substances (food), the correct answer to the question is phloem.

**Final Answer:** Bidirectional translocation of minerals takes place in phloem.
