Read the following statements and select the incorrect statement :-

Options

A. Members of kingdom fungi show a great diversity in morphology and habitat
B. Most fungi are saprophytic in their mode of nutrition
C. There are four classes under kingdom fungi
D. Some fungi are photosynthetic

Answer

To solve the question of identifying the incorrect statement about fungi, we will analyze each of the four statements provided.

### Step-by-Step Solution:

1. **Analyze Statement 1**: "Members of the kingdom fungi show a great diversity in morphology and habitat."
- **Explanation**: This statement is true. Fungi are known for their vast diversity in form (morphology) and can be found in various environments (habitats), including soil, water, and as parasites on plants and animals.

2. **Analyze Statement 2**: "Most fungi are saprophytic in their mode of nutrition."
- **Explanation**: This statement is also true. Most fungi obtain their nutrients by decomposing dead organic matter, which classifies them as saprophytes. They are heterotrophic organisms that rely on external sources for food.

3. **Analyze Statement 3**: "There are four classes under kingdom fungi."
- **Explanation**: This statement is true as well. The four main classes of fungi are:
- Phycomycetes
- Ascomycetes
- Basidiomycetes
- Deuteromycetes
Hence, this statement is correct.

4. **Analyze Statement 4**: "Some fungi are photosynthetic in nature."
- **Explanation**: This statement is incorrect. Fungi are heterotrophs and do not perform photosynthesis. They do not have chlorophyll and cannot produce their own food like plants do. Therefore, this statement is false.

### Conclusion:
The incorrect statement is **Statement 4**: "Some fungi are photosynthetic in nature."
