Naked (wall-less) , multinucleated and saprophytic organisms are grouped as ………….

Options

A. monerans
B. Protists
C. euglenoids
D. slime moulds

Answer

To solve the question regarding the classification of naked, wall-less, multinucleated, and saprophytic organisms, we will analyze each option provided and determine which group fits the description.

### Step-by-Step Solution:

1. **Understanding the Characteristics**:
- The organisms in question are described as naked (lacking a cell wall), multinucleated (having multiple nuclei), and saprophytic (feeding on decaying organic matter).

2. **Analyzing the Options**:
- **Option 1: Monerans**:
- Monerans are unicellular organisms that do not have a true nuclear membrane. They are primarily prokaryotic and do not fit the description of being multinucleated or saprophytic.
- **Conclusion**: This option is incorrect.

- **Option 2: Protists**:
- Protists are a diverse group of eukaryotic organisms. While some are unicellular and can be saprophytic, they are generally not multinucleated. They also possess a defined nucleus and can have cell walls.
- **Conclusion**: This option is incorrect.

- **Option 3: Euglenoids**:
- Euglenoids are a type of protist that are unicellular and flagellated. They lack a cell wall but have a flexible pellicle. They can be autotrophic or heterotrophic but are not typically described as multinucleated.
- **Conclusion**: This option is incorrect.

- **Option 4: Slime Molds**:
- Slime molds are indeed multinucleated, wall-less organisms that feed on decaying organic matter (saprophytic). They can exist in a plasmodial form where they are multinucleated and do not have a rigid cell wall.
- **Conclusion**: This option is correct.

3. **Final Answer**:
- Based on the analysis, the correct answer is **Slime Molds**.
