Answer

To solve the question of identifying the false statement, we will analyze each statement provided in the options.

### Step-by-Step Solution:

1. **Analyze the First Statement**:
- "Scientists who study and contribute to the classification of organisms are known as systematists."
- This statement is true. Systematists are indeed the scientists who classify organisms.

2. **Analyze the Second Statement**:
- "Phycomycetes are called the club fungus because of the club-shaped end of mycelium known as bacillium."
- This statement is false. Phycomycetes are not called club fungi; instead, it is the Basidiomycetes that are referred to as club fungi due to their club-shaped structures.

3. **Analyze the Third Statement**:
- "Carlos Linnaeus developed the first scientific system of classification."
- This statement is true. Linnaeus is known for creating the binomial nomenclature system for naming species.

4. **Analyze the Fourth Statement**:
- "The last one, a five kingdom arrangement of organisms, was introduced by R. H. Whittaker."
- This statement is also true. R.H. Whittaker is credited with proposing the five-kingdom classification system.

5. **Conclusion**:
- The false statement among the options is the one regarding Phycomycetes being called club fungi. Therefore, the correct answer to the question is that the statement about Phycomycetes is false.

### Final Answer:
The false statement is: "Phycomycetes are called the club fungus because of the club-shaped end of mycelium known as bacillium."
