Carbon assimilation takes place in

Options

A. mitochondria
B. chloroplast
C. cytoplasm
D. golgy body

Answer

To answer the question "Carbon assimilation takes place in," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Carbon Assimilation**:
- Carbon assimilation refers to the process of fixing carbon dioxide (CO2) into organic molecules. This process is crucial for photosynthesis, where plants convert CO2 into glucose.

2. **Identifying the Process in Photosynthesis**:
- Photosynthesis consists of two main phases: light reactions and dark reactions (Calvin cycle). Carbon assimilation primarily occurs during the dark reactions.

3. **Location of Photosynthesis**:
- Photosynthesis takes place in chloroplasts, which are specialized organelles found in plant cells. Chloroplasts contain the necessary machinery for both light and dark reactions.

4. **Examining the Options**:
- **Mitochondria**: Known as the powerhouse of the cell, involved in cellular respiration, not carbon assimilation.
- **Chloroplasts**: The correct answer, as they are the site of photosynthesis and carbon fixation.
- **Cytoplasm**: The fluid matrix of the cell, not specifically involved in carbon assimilation.
- **Golgi Bodies**: Involved in protein packaging and sorting, not related to carbon assimilation.

5. **Conclusion**:
- Based on the above analysis, the correct answer is **chloroplasts**.

### Final Answer:
Carbon assimilation takes place in **chloroplasts**.
