Products of photosynthesis are

Options

A. Carbon dioxide and food material
B. Carbohydrates and oxygen
C. Carbon dioxide and oxygen
D. Formaldehyde and nitrogen

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy. This process primarily occurs in the chloroplasts of plant cells.

2. **Reactants of Photosynthesis**: The main reactants involved in photosynthesis are carbon dioxide (CO2) and water (H2O). These are absorbed by the plant from the environment.

3. **Role of Light and Chlorophyll**: Light energy, usually from the sun, is captured by chlorophyll, the green pigment in plants. This energy is essential for driving the photosynthesis process.

4. **Overall Reaction of Photosynthesis**: The overall chemical equation for photosynthesis can be summarized as:
\[ 6 \text{CO}_2 + 12 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 + 6 \text{H}_2\text{O} \]
Here, glucose (C6H12O6) is produced along with oxygen (O2) and some water (H2O).

5. **Identifying the Products**: From the overall reaction, the main products of photosynthesis are glucose (a type of carbohydrate) and oxygen. The water produced is often not considered a primary product since it is also a reactant.

6. **Evaluating the Options**:
- **Option 1**: Carbon dioxide and food material - Incorrect, as carbon dioxide is a reactant, not a product.
- **Option 2**: Carbohydrates and oxygen - Correct, since glucose is a carbohydrate and oxygen is produced.
- **Option 3**: Carbon dioxide and oxygen - Incorrect, as carbon dioxide is a reactant.
- **Option 4**: Formaldehyde and nitrogen - Incorrect, as these are not products of photosynthesis.

7. **Conclusion**: The correct answer is that the products of photosynthesis are carbohydrates (specifically glucose) and oxygen.
