Which of the following are wall less procaryotes:-

Options

A. Mycoplasma
B. Bacteria
C. Cyanobacteria
D. Slime molds

Answer

To determine which of the following are wall-less prokaryotes, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- Option 1: Mycoplasma
- Option 2: Bacteria
- Option 3: Cyanobacteria
- Option 4: Slime mold

2. **Analyze Option 1: Mycoplasma**:
- Mycoplasma is a genus of bacteria that is known for lacking a cell wall. This characteristic makes it unique among prokaryotes. Therefore, **Mycoplasma is a wall-less prokaryote**.

3. **Analyze Option 2: Bacteria**:
- Bacteria typically have a cell wall, which is primarily composed of peptidoglycan. Since bacteria possess a cell wall, **this option is incorrect**.

4. **Analyze Option 3: Cyanobacteria**:
- Cyanobacteria, also known as blue-green algae, are a group of bacteria that perform photosynthesis. They also have a cell wall made of peptidoglycan. Thus, **this option is also incorrect**.

5. **Analyze Option 4: Slime mold**:
- Slime molds are not classified as prokaryotes; they are eukaryotic organisms. Additionally, slime molds have a cell wall made of cellulose. Therefore, **this option is incorrect as well**.

6. **Conclusion**:
- After analyzing all the options, we conclude that the only wall-less prokaryote among the given options is **Mycoplasma** (Option 1).

### Final Answer:
The correct answer is **Option 1: Mycoplasma**.
