Naked (wall-less) , multinucleated and saprophytic organisms are grouped as ………….
(a) monerans
(b) Protists
(c) euglenoids
(d) slime moulds

Options

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

Answer

To solve the question "Naked (wall-less), multinucleated and saprophytic organisms are grouped as ………….", we can analyze each option step by step.

### Step 1: Understand the characteristics of the organisms in question
The question describes organisms that are:
- Naked (wall-less)
- Multinucleated
- Saprophytic (feeding on dead or decaying organic matter)

### Step 2: Evaluate the options
**(a) Monerans**
- Monerans include bacteria and blue-green algae (BGA).
- These organisms typically have a cell wall and are not multinucleated.
- **Conclusion**: This option is incorrect.

**(b) Protists**
- Protists are a diverse group of organisms that can exhibit various modes of nutrition.
- However, most protists are not saprophytic and typically have a cell membrane.
- **Conclusion**: This option is incorrect.

**(c) Euglenoids**
- Euglenoids are a type of protist that can perform photosynthesis and are not typically saprophytic.
- They also have a cell membrane and are not multinucleated.
- **Conclusion**: This option is incorrect.

**(d) Slime moulds**
- Slime moulds are a type of saprophytic protist.
- They are known to be multinucleated and do not have a cell wall, existing in a form that resembles a plasmodium (a mass of protoplasm).
- They feed on dead and decaying organic matter.
- **Conclusion**: This option is correct.

### Final Answer
The correct answer is **(d) slime moulds**.
