Select the incorrect statement in the following

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 determine the incorrect statement among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement A: Chrysophytes are found in freshwater as well as in marine environments.**
- **Analysis:** Chrysophytes, also known as golden algae, are indeed found in both freshwater and marine environments. They are important producers in aquatic ecosystems.
- **Conclusion:** This statement is **true**.

2. **Statement B: Dinoflagellates have two flagella and are mostly freshwater organisms.**
- **Analysis:** Dinoflagellates are characterized by having two flagella, but they are primarily marine organisms, not mostly freshwater. While some species can be found in freshwater, the majority thrive in marine environments.
- **Conclusion:** This statement is **false**.

3. **Statement C: Majority of euglenoids are freshwater organisms and they have a protein-rich layer called pellicle instead of a cell wall.**
- **Analysis:** Euglenoids, such as Euglena, are predominantly found in freshwater environments. They do have a pellicle, which is a flexible protein layer that allows them to maintain their shape.
- **Conclusion:** This statement is **true**.

4. **Statement D: Slime molds are saprophytic protists.**
- **Analysis:** Slime molds are indeed saprophytic, meaning they feed on decaying organic matter. They play a crucial role in nutrient cycling in ecosystems.
- **Conclusion:** This statement is **true**.

### Final Conclusion:
- The incorrect statement among the options provided is **Statement B**: "Dinoflagellates have two flagella and are mostly freshwater organisms."
