The technique of growing plants without soil in nutrient solutions is called

Options

A. Parthenogenesis
B. Hydroponics
C. Aquaculture
D. Tissue culture

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the technique used to grow plants without soil, specifically in nutrient solutions.

2. **Analyzing the Options**: The options given are:
- A) Partinogenesis
- B) Hydrophonics
- C) Aquaculture
- D) Tissue Culture

3. **Defining Each Option**:
- **Partinogenesis**: This term refers to a form of asexual reproduction where an egg develops into an organism without fertilization. This is not related to plant growth in nutrient solutions.
- **Hydrophonics**: This is the correct term for growing plants in a water-based, nutrient-rich solution without soil.
- **Aquaculture**: This refers to the farming of aquatic organisms, such as fish and shellfish, and is not specifically about growing plants.
- **Tissue Culture**: This is a technique used to grow cells or tissues in a controlled environment, but it does not refer to growing plants in nutrient solutions.

4. **Identifying the Correct Answer**: Based on the definitions, Hydrophonics (Option B) is the technique that allows plants to grow without soil, utilizing a nutrient solution.

5. **Conclusion**: Therefore, the answer to the question is **Hydrophonics**.
