Options

A. `1-10`
B. `10-20`
C. `20-30`
D. `30-40`

Answer

To answer the question about the average number of chloroplasts present in mesophyll cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mesophyll Cells**:
- Mesophyll cells are specialized cells found in the leaves of plants. They are primarily involved in photosynthesis, which is the process of converting light energy into chemical energy.

2. **Role of Chloroplasts**:
- Chloroplasts are the organelles within mesophyll cells where photosynthesis takes place. They contain chlorophyll, the pigment that captures light energy.

3. **Average Number of Chloroplasts**:
- Research and studies indicate that the average number of chloroplasts found in mesophyll cells ranges from 20 to 30 per cell. This number can vary depending on the type of plant.

4. **Variation Among Different Organisms**:
- It's important to note that the number of chloroplasts can differ significantly between different plant species and other organisms. For example, some algal cells may contain only one chloroplast.

5. **Conclusion**:
- Therefore, the average number of chloroplasts in mesophyll cells is typically between 20 to 30.

### Final Answer:
The average number of chloroplasts present in mesophyll cells is **20 to 30**.
