The abscent of minerals is

Options

A. equal to the rate of translocation of water
B. dependent on transpiration pull
C. through xylem vessel
D. All of the above

Answer

### Step-by-Step Solution:

1. **Understanding the Concept**: The question refers to the absence of minerals in plants and its implications. Minerals are essential for various physiological processes in plants, including water transport.

2. **Translocation of Water**: In plants, water is primarily transported through xylem vessels. The process of water movement is known as translocation.

3. **Role of Transpiration**: Transpiration is the process through which water evaporates from the surface of leaves. This creates a negative pressure (transpiration pull) that helps in pulling water upward from the roots through the xylem.

4. **Linking Absence of Minerals**: When minerals are absent, it can affect the plant's ability to maintain proper physiological functions, including the rate of water translocation. The absence of minerals can lead to reduced transpiration rates, which in turn affects the water transport mechanism.

5. **Conclusion**: Therefore, the absence of minerals is equal to the rate of translocation of water, which is dependent on the transpiration pull through xylem vessels. Thus, the correct option is "all of the above."
