mark the odd one ( w.r.t internal factors affecting photosythesis )

Options

A. Amount of chlorophyll
B. Light intensity
C. Mesophyll cells
D. Orientation of leaves

Answer

To solve the question of marking the odd one out with respect to internal factors affecting photosynthesis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Internal Factors**:
- Internal factors affecting photosynthesis include components that are part of the plant's structure and physiology. Examples are:
- Amount of chlorophyll
- Mesophyll cells
- Orientation of leaves

2. **Identify External Factors**:
- External factors are environmental conditions that influence photosynthesis but are not part of the plant's internal structure. Examples include:
- Light intensity
- Temperature
- Concentration of CO2
- Availability of water

3. **Analyze the Options**:
- From the question, we need to analyze the given options to determine which one does not belong to the category of internal factors.
- The options likely include:
- Amount of chlorophyll (internal)
- Mesophyll cells (internal)
- Orientation of leaves (internal)
- Light intensity (external)

4. **Determine the Odd One Out**:
- Among the options, light intensity is the only factor that is external to the plant. Therefore, it does not fit with the internal factors affecting photosynthesis.

5. **Conclusion**:
- The odd one out with respect to internal factors affecting photosynthesis is **light intensity**.
