The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. This process primarily occurs in the chloroplasts of plant cells. 2. **Chemical Equation of Photosynthesis**: The overall chemical equation for photosynthesis can be summarized as: \[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \] Here, carbon dioxide (CO2) and water (H2O) are the reactants, and glucose (C6H12O6) and oxygen (O2) are the products. 3. **Oxidation and Reduction**: - **Oxidation** is the loss of electrons or an increase in oxidation state. - **Reduction** is the gain of electrons or a decrease in oxidation state. In photosynthesis: - Water (H2O) is oxidized to oxygen (O2). - Carbon dioxide (CO2) is reduced to glucose (C6H12O6). 4. **Analyzing Oxidation States**: - In water (H2O), the oxidation state of oxygen is -2. When water is oxidized to oxygen (O2), the oxidation state of oxygen increases to 0. - In carbon dioxide (CO2), the oxidation state of carbon is +4. When carbon dioxide is reduced to glucose (C6H12O6), the oxidation state of carbon decreases to 0. 5. **Conclusion**: From the analysis, we can conclude: - Water is oxidized (loses electrons). - Carbon dioxide is reduced (gains electrons). Therefore, the correct statement regarding the processes occurring during photosynthesis is that **water is oxidized and carbon dioxide is reduced**. ### Final Answer: The correct option is: **CO2 gets reduced and water gets oxidized.** ---
