Photosynthesis in plants is dependent on all of the following factors except

Options

A. intensity, duration and quality of light
B. availability of sufficient carbon dloxide and water
C. content of chlorophyll and structure of leaves
D. presence of other species of trees in the surrounding

Answer

To answer the question about the factors on which photosynthesis in plants is dependent, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.
- Key components required for photosynthesis include sunlight, chlorophyll, carbon dioxide, and water.

2. **Identifying Factors Affecting Photosynthesis**:
- **Intensity of Light**: The amount of light available affects the rate of photosynthesis. Higher light intensity generally increases the rate of photosynthesis up to a certain point.
- **Duration of Light**: The length of time that light is available each day can also influence photosynthesis. Longer durations can enhance the process.
- **Quality of Light**: Different wavelengths of light can affect photosynthesis. Chlorophyll primarily absorbs blue and red light, so the quality of light is important.
- **Availability of Carbon Dioxide and Water**: Both are essential raw materials for photosynthesis. Without sufficient amounts, the process cannot occur effectively.
- **Content of Chlorophyll and Structure of Leaves**: Chlorophyll is necessary for capturing light energy, and the structure of leaves (such as surface area and thickness) can influence how effectively photosynthesis occurs.

3. **Evaluating the Options**:
- Now, we need to evaluate the options given in the question:
- A. Intensity of light
- B. Duration of light
- C. Quality of light
- D. Presence of other species of trees in the surrounding

4. **Determining the Incorrect Factor**:
- Options A, B, C, and D are all factors that can influence photosynthesis. However, the presence of other species of trees in the surrounding does not directly affect the photosynthesis process of a specific plant. While it may influence competition for resources, it is not a direct requirement for photosynthesis itself.

5. **Conclusion**:
- Therefore, the correct answer to the question is **D. Presence of other species of trees in the surrounding**.
