Which of the following statements is incorrect

Options

A. Water and salts are taken simultaneously by root hairs
B. Plants absorb one thing at a time either water or inorganic salt
C. Plants absorb an excess quantity of water
D. All of the above

Explanation

To determine which statement is incorrect regarding the transport in plants, we will analyze the statements one by one.

### Step-by-Step Solution:

1. **Understanding Root Hairs Function**:
- Root hairs are specialized structures on plant roots that increase the surface area for absorption. They primarily absorb water and dissolved minerals from the soil.
- **Hint**: Recall the role of root hairs in enhancing water and nutrient uptake.

2. **Evaluating Statement 1**:
- The first statement claims that "water and salts are taken simultaneously by root hairs." This statement is correct because root hairs can absorb both water and minerals at the same time through osmosis and active transport.
- **Hint**: Think about how root hairs interact with the soil solution to absorb nutrients.

3. **Evaluating Statement 2**:
- The second statement suggests that "plants absorb one thing at a time, either water or inorganic salt." This statement is incorrect. Plants can absorb both water and inorganic salts simultaneously through root hairs.
- **Hint**: Consider the mechanisms of absorption in plants and how they function together.

4. **Evaluating Statement 3**:
- The third statement states that "plants absorb an excess quantity of water." This is generally true, as plants can take up more water than they need, which they can store or lose through transpiration.
- **Hint**: Reflect on how plants manage water intake and loss.

5. **Final Conclusion**:
- Based on the analysis, the incorrect statement is the second one: "plants absorb one thing at a time, either water or inorganic salt." This is not true as plants can absorb both simultaneously.

### Answer:
The incorrect statement is: **"Plants absorb one thing at a time, either water or inorganic salt."**
