Temperature range for plant growth is

Options

A. `20^(@)-35^(@)`
B. `0^(@)-35^(@)C`
C. `10^(@)-50^(@)`
D. `0^(@)-20^(@)C`

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the temperature range that is optimal for plant growth. This means we need to identify the temperature range within which most plants thrive and exhibit healthy growth.

2. **Identifying Factors Affecting Plant Growth**: Plant growth is influenced by several factors, including temperature. Each plant species has its own specific temperature range that is optimal for growth.

3. **Exploring the Options**: The options provided are:
- A) 20 to 35 degrees Celsius
- B) 0 to 35 degrees Celsius
- C) 10 to 50 degrees Celsius
- D) 0 to 20 degrees Celsius

4. **Analyzing the Temperature Ranges**:
- **Option A (20 to 35°C)**: This range is somewhat limited and may not cover all plant species.
- **Option B (0 to 35°C)**: This range includes a wider spectrum, allowing for various plant species to thrive.
- **Option C (10 to 50°C)**: This range is too broad and includes temperatures that can be harmful to many plants.
- **Option D (0 to 20°C)**: This range is too low for many plants, especially those that require warmer conditions.

5. **Determining the Correct Option**: Based on the analysis, the optimal temperature range for most plants is between **0 to 35 degrees Celsius**. This range allows for essential processes such as photosynthesis, respiration, and protein synthesis to occur effectively.

6. **Conclusion**: Therefore, the correct answer to the question regarding the temperature range for plant growth is **B) 0 to 35 degrees Celsius**.
