In a certain experiment, plant cells are allowed to grow in a nutrient medium. The cell culture is kept in a dark room. After a week, they are removed and studied. It can be concluded from the above experiment that

Options

A. all cells will die
B. cells will perform photosynthesis, multiply, and grow
C. photosynthetic cells will die
D. cells will be alive but will not perform photosynthesis

Answer

**Step-by-Step Solution:**

1. **Understanding the Experiment**: The experiment involves plant cells growing in a nutrient medium in a dark room for a week. This setup is crucial for analyzing the effects of light on plant cells.

2. **Nutrient Medium**: The cells are provided with a nutrient medium, which supplies essential nutrients required for growth. This means that the cells have the necessary materials for cellular metabolism and growth.

3. **Absence of Light**: The cells are kept in a dark room, meaning there is no light available for photosynthesis. Photosynthesis is the process by which plants convert light energy into chemical energy (glucose) using chlorophyll, carbon dioxide, and water.

4. **Photosynthesis Requirement**: Since photosynthesis requires light, and the cells are in darkness, they will not be able to perform this process. Therefore, any conclusions regarding photosynthesis in this scenario must take into account the lack of light.

5. **Conclusion About Cell Viability**: Despite the absence of light, the plant cells will not die because they are receiving nutrients from the medium. They can survive and carry out other metabolic processes that do not require light.

6. **Final Conclusion**: The correct conclusion from the experiment is that the plant cells will remain alive but will not be able to perform photosynthesis due to the lack of light.

**Final Answer**: The plant cells will be alive but will not perform photosynthesis.
