Answer

To solve the question "Which one of the following is not a correct statement?", we will analyze each of the four provided statements one by one to identify the incorrect one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Key is a taxonomic aid for identification of specimen."
- **Evaluation:** This statement is correct. A key is indeed a taxonomic tool used to identify organisms based on their characteristics.

2. **Analyze the Second Statement:**
- **Statement:** "Herbarium houses dried, pressed and preserved plant specimens."
- **Evaluation:** This statement is also correct. A herbarium is a collection where plant specimens are stored in a dried and pressed form for study and reference.

3. **Analyze the Third Statement:**
- **Statement:** "Botanical Gardens have a collection of living plants for reference."
- **Evaluation:** This statement is correct as well. Botanical gardens are designed to cultivate and display a variety of living plants, often for educational and research purposes.

4. **Analyze the Fourth Statement:**
- **Statement:** "Museum has a collection of photographs of plants and animals."
- **Evaluation:** This statement is incorrect. Museums typically house actual specimens (preserved plants and animals) rather than just photographs.

### Conclusion:
The statement that is not correct is the fourth one: "Museum has a collection of photographs of plants and animals."

### Final Answer:
The incorrect statement is option 4.
