If there is high amount of fertilizer present in soil &it is deficient in water then what will be the effect

Options

A. Over growth
B. Synthesis of chlorophyll increases
C. No effect
D. Wilting of plants

Answer

### Step-by-Step Solution:

1. **Understanding the Situation**: The question states that there is a high amount of fertilizer present in the soil, but the soil is deficient in water. This creates a specific condition for the plants.

2. **Analyzing Water Potential**: Water potential is a measure that indicates the potential energy of water in a system, which influences the movement of water. In this case, the high concentration of fertilizer in the soil will lower the water potential because the presence of solutes (fertilizers) reduces the concentration of free water molecules.

3. **Effect on Water Absorption**: Due to the low water potential in the soil (caused by high fertilizer concentration), the roots of the plants will struggle to absorb water. This is because water moves from areas of higher water potential to areas of lower water potential, and the soil's low water potential makes it difficult for the roots to take up water.

4. **Consequences for the Plants**: When plants cannot absorb sufficient water, they will begin to exhibit signs of stress. One of the most common symptoms of water deficiency is wilting. Wilting occurs when the plant cells lose turgor pressure due to lack of water, leading to drooping leaves and stems.

5. **Evaluating Options**:
- **Overgrowth**: This option is incorrect because overgrowth typically requires both adequate water and nutrients.
- **Synthesis of Chlorophyll Increases**: This option is also incorrect; chlorophyll synthesis requires sufficient water and light.
- **No Effect**: This option is incorrect as well; the lack of water will definitely have an effect on the plants.
- **Wilting of Plants**: This is the correct option, as wilting is a direct result of insufficient water availability.

6. **Conclusion**: The correct answer to the question is that the plants will experience wilting due to the high fertilizer concentration and low water availability in the soil.
