Select the non-protistan group.

Options

A. Slime moulds
B. Dinoflagellates
C. Phycomycetes
D. Chrysophytes

Answer

To solve the question of selecting the non-protistan group from the options provided (slime molds, dinoflagellates, phycomycetes, or chrysophytes), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Kingdoms**:
- The question revolves around identifying which of the given groups does not belong to the kingdom Protista.
- The kingdom Protista primarily includes unicellular eukaryotic organisms.

2. **Analyze Each Option**:
- **Slime Molds**: These are protists that exhibit characteristics of both fungi and amoebas. They are unicellular eukaryotes and belong to the kingdom Protista.
- **Dinoflagellates**: These are also unicellular eukaryotic organisms, often found in marine environments. They possess flagella and are classified under the kingdom Protista.
- **Chrysophytes**: This group includes organisms like diatoms and desmids, which are also unicellular eukaryotes and belong to the kingdom Protista.
- **Phycomycetes**: This group represents fungi, which are multicellular eukaryotic organisms that are heterotrophic and derive nutrients from other organisms. They belong to the kingdom Fungi, not Protista.

3. **Identify the Non-Protistan Group**:
- From the analysis, it is clear that phycomycetes is the only group that does not belong to the kingdom Protista. Instead, it belongs to the kingdom Fungi.

4. **Conclusion**:
- Therefore, the non-protistan group among the options provided is **phycomycetes**.

### Final Answer:
**Phycomycetes**
