Find the incorrect match from the following

Options

A. plant factors of photosynthesis dependent on `rarr` genetic predisposition and growth of the plant
B. temperature optimum for photosynthesis of different plant depends `rarr` only on the habitat to which they are adapted
C. effect of water as a factor on photosynthesis is `rarr` indirect
D. major limiting factor for photosynthesis `rarrCO_(2)`

Answer

To find the incorrect match from the given statements regarding photosynthesis, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement 1: Plant factors of photosynthesis depend on predisposition and growth of plant which we call genetic factor.**
- This statement is correct. Plant factors indeed depend on genetic predisposition and growth characteristics, such as leaf size, number of leaves, and chloroplast content, which are all influenced by the plant's genetics.

2. **Statement 2: Temperature optimum for photosynthesis of different plants depends only on habitat to which they are adapted.**
- This statement is incorrect. While habitat does influence the temperature optimum for photosynthesis, it is not the only factor. Different plants have specific temperature requirements based on their physiological adaptations. For example, C3 plants typically have an optimum temperature range of 20-25°C, while C4 plants have a range of 30-40°C. Therefore, this statement is misleading as it suggests that habitat is the sole determinant.

3. **Statement 3: Effect of water on photosynthesis is indirect.**
- This statement is correct. Water is essential for photosynthesis, but its effect is considered indirect. Plants use a small fraction of the water they absorb for photosynthesis, and the lack of water can lead to wilting and reduced photosynthesis due to stomatal closure. Thus, the relationship between water and photosynthesis is indirect.

4. **Statement 4: Major limiting factor for photosynthesis is carbon dioxide.**
- This statement is correct. According to Blackman's law of limiting factors, the factor that is in the least supply will limit the rate of photosynthesis. Since atmospheric carbon dioxide is present in low concentrations (about 0.3-0.4%), it can be a limiting factor for photosynthesis. Increasing carbon dioxide levels can enhance the rate of photosynthesis.

### Conclusion:
The incorrect match from the statements provided is **Statement 2**: "Temperature optimum for photosynthesis of different plants depends only on habitat to which they are adapted."
