Which of the following is correct for respiration in plants?

Options

A. Respiration takes place only during day time.
B. Respiration takes place only during night.
C. Respiration takes place both during day and night.
D. Respiration takes place only when plants are not making food.

Answer

**Step-by-Step Solution:**

1. **Understanding Respiration**: Respiration is a biological process essential for survival. It involves the intake of oxygen and the release of carbon dioxide as a waste product. This process is crucial for energy production in living organisms.

2. **Energy Production**: During respiration, nutrients obtained from food are broken down, releasing energy that is used for various bodily functions.

3. **Respiration in Plants**: Plants also undergo respiration, similar to animals. They require oxygen to respire and produce carbon dioxide as a byproduct.

4. **Analyzing the Options**:
- **Option 1**: "Respiration takes place only during daytime." This is incorrect because plants respire both day and night.
- **Option 2**: "Respiration takes place only during night." This is also incorrect for the same reason; plants respire continuously.
- **Option 3**: "Respiration takes place both during day and night." This is correct as plants require energy at all times, regardless of whether it is day or night.
- **Option 4**: "Respiration takes place only when plants are not making food." This is incorrect because plants need energy for respiration even when they are photosynthesizing.

5. **Conclusion**: The correct answer is **Option 3**, which states that respiration takes place both during day and night.
