Answer

### Step-by-Step Solution:

1. **Understanding Herbarium**: Begin by defining what a herbarium is. A herbarium is a collection of preserved plant specimens that are systematically arranged and stored.

2. **Analyzing the Statements**: The question asks to identify the incorrect statement about herbarium. We need to evaluate each statement provided.

3. **Statement Evaluation**:
- **Statement 1**: "It is a storehouse of collected dry plant specimens and we have pressed it on a particular sheet."
- This statement is correct as it accurately describes the purpose and method of creating herbarium sheets.

- **Statement 2**: "It consists of many herbarium sheets arranged in a universally accepted system of classification."
- This statement is also correct. Herbarium sheets are indeed arranged systematically according to classification systems.

- **Statement 3**: "Herbarium sheets also carry labels with a complete photo profile of a collector of specimens."
- This statement is incorrect. While herbarium sheets do carry labels, they typically include information about the plant specimen itself (such as the scientific name, common name, collection location, and date), not a complete photo profile of the collector.

- **Statement 4**: "Herbarium also serves as a quick referral system for taxonomic studies."
- This statement is correct. Herbarium sheets are used as references in taxonomic studies.

4. **Identifying the Incorrect Statement**: Based on the evaluation, Statement 3 is the incorrect statement regarding herbarium.

5. **Conclusion**: The incorrect statement about herbarium is that it carries a complete photo profile of the collector, which is not necessary. Instead, it should focus on the plant profile.
