#### Fill out the table below:

| | Cellular Respiration | Photosynthesis |
|---------------|---------------------------|---------------------|
| Reactants | Glucose (C₆H₁₂O₆) + Oxygen (O₂) | Carbon dioxide (CO₂) + Water (H₂O) + Sunlight energy |
| Products | Carbon dioxide (CO₂) + Water (H₂O) + ATP (energy) | Glucose (C₆H₁₂O₆) + Oxygen (O₂) |
| What organelle? | Mitochondria | Chloroplasts |

#### 12. Use the picture to the right to help you describe the relationship between photosynthesis and cellular respiration:

- Photosynthesis occurs in chloroplasts and uses sunlight energy, carbon dioxide (CO₂), and water (H₂O) to produce glucose (C₆H₁₂O₆) and oxygen (O₂). This process stores energy in the form of glucose.
- Cellular respiration occurs in mitochondria and uses glucose (C₆H₁₂O₆) and oxygen (O₂) to produce carbon dioxide (CO₂), water (H₂O), and ATP (adenosine triphosphate), which is the energy currency of cells.
- The relationship is cyclical:
- Photosynthesis produces glucose and oxygen, which are essential for cellular respiration.
- Cellular respiration breaks down glucose to release energy (ATP) and produces carbon dioxide and water, which are used in photosynthesis.
- This cycle ensures a continuous flow of energy and matter within ecosystems.

#### 13. What kind(s) of organisms perform photosynthesis?

- Answer: Photosynthesis is primarily performed by autotrophs, including plants, algae, and certain bacteria. These organisms use sunlight to convert carbon dioxide and water into glucose and oxygen.

---

#### 14. What kind(s) of organisms perform cellular respiration?

- Answer: Cellular respiration is performed by all living organisms, including plants, animals, fungi, and bacteria. Both autotrophs (e.g., plants) and heterotrophs (e.g., animals) rely on cellular respiration to generate energy from glucose.

Final Answer Summary:

1. J. Autotrophs
2. A. Chloroplasts
3. G. Glycolysis
4. D. Glucose
5. B. Anaerobic
6. C. Aerobic
7. E. ATP
8. E. ATP (or I. ADP)
9. G. Glycolysis
10. H. Energy

Table:
- Cellular Respiration: Reactants = Glucose + Oxygen; Products = CO₂ + H₂O + ATP; Organelle = Mitochondria
- Photosynthesis: Reactants = CO₂ + H₂O + Sunlight; Products = Glucose + O₂; Organelle = Chloroplasts

Relationship: Photosynthesis produces glucose and oxygen, which are used in cellular respiration to generate ATP and release CO₂ and H₂O, completing the cycle.

Organisms performing photosynthesis: Plants, algae, and certain bacteria.
Organisms performing cellular respiration: All living organisms.
