Options

A. Chrysophytes are found in fresh water as well as in marine environment.
B. Dinoflagellates are mostly fresh water organisms and photosynthetic.
C. Majority of euglenoids are fresh water organisms.
D. Slime moulds are saprophytic protist

Answer

To solve the question of identifying the incorrect statement about members of the Protista kingdom, we can follow these steps:

### Step-by-Step Solution:

1. **Analyze the First Statement**:
- The statement claims that "Creosophytes are found in fresh water as well as marine water environments."
- This statement is **correct** because creosophytes can indeed be found in both freshwater and marine environments.

2. **Analyze the Second Statement**:
- The statement claims that "Dinoflagellates are mostly freshwater organisms and photosynthetic."
- This statement is **incorrect** because dinoflagellates are primarily marine organisms, although some can be found in freshwater. However, the emphasis on "mostly freshwater" makes this statement wrong.

3. **Analyze the Third Statement**:
- The statement claims that "Majority of Euglinoids are freshwater organisms."
- This statement is **correct** as Euglinoids are predominantly found in freshwater environments and are known for their photosynthetic abilities.

4. **Analyze the Fourth Statement**:
- The statement claims that "Slime molds are saprophytic protists."
- This statement is **correct** because slime molds exhibit saprophytic behavior, similar to fungi.

5. **Conclusion**:
- After analyzing all statements, the incorrect statement is the second one regarding dinoflagellates being mostly freshwater organisms. Therefore, the answer is option number 2.

### Final Answer:
The incorrect statement is: "Dinoflagellates are mostly freshwater organisms and photosynthetic."
