Which of the following is incorrect about excretion in plants?

Options

A. Production of rubber, resin, etc., is a means of excretion for plants.
B. Transpiration helps plants to get rid of excess water.
C. Withering leaves accumulate excretory wastes.
D. None of these

Explanation

To determine which statement is incorrect about excretion in plants, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Excretion in Plants**:
- Excretion refers to the process of removing waste materials from the body of an organism. In plants, this can include various substances that are byproducts of metabolic processes.

2. **Analyzing the Statements**:
- **Statement 1**: "Production of rubber, resins, etc. is a means of excretion for plants."
- This statement is correct. Some plants produce substances like rubber and resins, which can be considered waste products that are excreted.

- **Statement 2**: "Transpiration helps plants to get rid of excess water."
- This statement is also correct. Transpiration is the process where plants lose water vapor through small openings in their leaves, helping to regulate water balance.

- **Statement 3**: "Withering leaves accumulate excretory waste."
- This statement is misleading. While leaves do eventually wither and fall off, they do not accumulate waste in a way that is retained within the plant. Instead, the waste is effectively removed when the leaves senesce and detach from the plant.

3. **Identifying the Incorrect Statement**:
- Based on the analysis, the third statement is incorrect because it implies that withering leaves retain waste, which is not true. Instead, the waste is removed when the leaves fall off.

### Conclusion:
The incorrect statement about excretion in plants is **"Withering leaves accumulate excretory waste."**
