A student sets up an experiment on photosynthesis and it is as follows : He takes soda water in a glass tumbler and adds chlorophyll extract into the contents and keeps the tumbler exposed to sun light, hoping that he was provided the ingredients. What will happen after, say, a few hours of exposure to light ? Choose the correct answer.

Options

A. Photosynthesis takes place and glucose would be produced turning the mixture sweet
B. Photosynthesis will take place and starch would be produced which will turn the mixture turbid
C. Photosynthesis does not occur and `CO_(2)` dissolved 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 the Experiment Setup**:
The student has taken soda water, which contains dissolved carbon dioxide (CO2), and added chlorophyll extract. The tumbler is then exposed to sunlight.

2. **Role of Chlorophyll**:
Chlorophyll is essential for photosynthesis as it captures light energy. However, in this experiment, the chlorophyll is in an extract form and not in intact chloroplasts.

3. **Photosynthesis Requirements**:
For photosynthesis to occur, intact chloroplasts are necessary. This is because the photosystems (PS1 and PS2) need to work together in a coordinated manner, which is not possible when chlorophyll is separated from its cellular structures.

4. **Expected Outcome**:
Since the chlorophyll is extracted and not in its natural form, the necessary structures for photosynthesis are not present. Therefore, photosynthesis cannot take place.

5. **Conclusion**:
After a few hours of exposure to sunlight, photosynthesis will not occur, and the CO2 dissolved in the soda water will not be utilized for photosynthesis.

### Final Answer:
The correct answer is that photosynthesis does not occur due to the lack of intact chloroplasts, and thus, glucose or starch will not be produced.
