Hydroponics is the method of

Options

A. water conservation
B. plant development in water without soil
C. plant development without soil
D. plant development in saline soil

Answer

**Step-by-Step Solution:**

1. **Definition of Hydroponics**: Hydroponics is a method of growing plants without soil. The term "hydro" means water, indicating that this method relies primarily on water as a medium for plant growth.

2. **Substrate for Growth**: In hydroponics, water serves as the substrate instead of soil. This means that the plants are supported and nourished directly in a water-based environment.

3. **Nutrient Solution**: To ensure that plants receive the necessary nutrients for growth, fertilizers are added to the water. This creates a nutrient solution that provides all essential minerals and nutrients required by the plants.

4. **Components of Hydroponics System**: A typical hydroponics system includes various components such as:
- Nutritional solution (water mixed with fertilizers)
- Air bubbles or aeration systems to provide oxygen to the plant roots
- Water circulation pumps to maintain the flow of the nutrient solution

5. **Plant Development**: The plants are cultivated in this nutrient-rich water environment, allowing them to grow efficiently without the need for soil.

6. **Conclusion**: Hydroponics is an innovative agricultural method that allows for efficient plant growth using water and nutrient solutions, making it a sustainable practice for food production.
