Respiration is seen in

Options

A. Non green cells only
B. None green cells in light only
C. All living cells
D. All cells, except the photosynthetic cells during day

Answer

**Step-by-Step Text Solution:**

1. **Understanding Respiration**: Respiration is a biochemical process that involves the oxidation or breakdown of food substances (organic compounds) to release energy. This energy is essential for various metabolic activities in living organisms.

2. **Identifying the Need for Respiration**: All living cells require energy to perform physiological and metabolic activities. Therefore, respiration is a fundamental process necessary for the survival of all living cells.

3. **Analyzing the Options**:
- **Option A**: "Respiration is seen only in non-green cells." This is incorrect because all cells, including green cells (which perform photosynthesis), require energy and thus respire.
- **Option B**: "Respiration is seen in non-green cells in light only." This statement is misleading as respiration occurs in all living cells regardless of light conditions.
- **Option C**: "Respiration is seen in all living cells." This is the correct statement because all living cells, including those that are photosynthetic, require energy and thus perform respiration.
- **Option D**: "Respiration is seen in all cells except the photosynthetic cells during the day." This is incorrect because photosynthetic cells also respire to obtain energy.

4. **Conclusion**: The correct answer is **Option C**: "Respiration is seen in all living cells."
