In plants, respiration takes place

Options

A. During day only
B. During night only
C. All 24 hours
D. At dusk

Answer

**Step-by-Step Solution:**

1. **Understanding Respiration in Plants**: Respiration is a biochemical process where plants convert glucose and oxygen into energy, carbon dioxide, and water. This process is essential for the growth and maintenance of plant cells.

2. **Differentiating Between Photosynthesis and Respiration**: Photosynthesis is a light-dependent process that occurs in the presence of sunlight, primarily in the chloroplasts of green plants. It involves the conversion of light energy into chemical energy (glucose). In contrast, respiration does not depend on light.

3. **Light Dependence of Photosynthesis**: During the day, plants perform photosynthesis, which requires light. This process produces glucose and oxygen, which are then used in respiration.

4. **Respiration Occurs All the Time**: Unlike photosynthesis, respiration is a continuous process. It occurs both during the day and at night, meaning it takes place 24 hours a day. This is because respiration does not involve any photochemical reactions and can occur in the presence or absence of light.

5. **Conclusion**: Therefore, in plants, respiration takes place all 24 hours, regardless of whether it is day or night.
