A student sets up an expirment on photoysthesis as folows :
He takes soda water in a glass tumbler and adds chloroplyll into the contents and keeps the tumbler exposed to sunlight hoping that he has provided necessary ingredients for photosynthesis to proceed ( viz. `CO_(2), H_(2)O,` chlorophyll, and light). What do you think what happens after, say a few hours of exposure of light ?

Options

A. Photosynthesis will take place and glucose will be produced
B. Photosynthesis will take place and starch will be produced which trun the mixture turbid.
C. Photosynthesis will not take place because `CO_(2)` dissoved in soda water escapes into the atmosphere
D. Photosynthesis will not take place because intact chloroplasts are needed for the process.

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants use sunlight to synthesize foods (mainly glucose) from carbon dioxide (CO2) and water (H2O). This process requires chlorophyll, the green pigment found in plants, which captures light energy.

2. **Components of the Experiment**: In the student's experiment, he has provided the following necessary components for photosynthesis:
- **Soda Water**: Contains dissolved CO2 and H2O.
- **Chlorophyll**: The pigment required for capturing light energy.
- **Sunlight**: The energy source for the photosynthesis process.

3. **Setting Up the Experiment**: The student sets up the experiment by mixing chlorophyll into soda water and exposing it to sunlight. He believes that with all the necessary ingredients present, photosynthesis should occur.

4. **Analyzing the Conditions for Photosynthesis**: Despite having CO2, H2O, chlorophyll, and light, the experiment lacks a crucial element:
- **Intact Chloroplasts**: Photosynthesis occurs in the chloroplasts of plant cells, which contain the necessary cellular machinery to convert light energy into chemical energy.

5. **Conclusion**: Since the chlorophyll is not in a living plant cell with intact chloroplasts, photosynthesis will not occur in this experimental setup. The chlorophyll added to the soda water does not have the cellular structures required for the process.

6. **Final Answer**: Therefore, the correct conclusion is that photosynthesis will not occur because intact chloroplasts are needed for the process.
