Electron microscopic observation reveals the absence of intracellular membranes in the cell of

Options

A. Eucaryota
B. Mycota
C. Thallophyta
D. Procaryota

Answer

To solve the question regarding the absence of intracellular membranes in a cell observed under an electron microscope, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which type of cell lacks intracellular membranes. Intracellular membranes are typically found in eukaryotic cells, which contain membrane-bound organelles.

2. **Identifying Cell Types**: We need to consider the four options provided: Eukaryota, Mycota, Thallophyta, and Prokaryota.

3. **Analyzing Eukaryota**:
- Eukaryotic cells are characterized by the presence of a true nucleus and membrane-bound organelles (like mitochondria, endoplasmic reticulum, etc.).
- Therefore, Eukaryota cannot be the answer since it has intracellular membranes.

4. **Analyzing Mycota**:
- Mycota refers to fungi, which are also eukaryotic organisms.
- They have a true nucleus and membrane-bound organelles.
- Thus, Mycota cannot be the answer either.

5. **Analyzing Thallophyta**:
- Thallophyta includes simple plants (like algae) that are also eukaryotic.
- They possess a true nucleus and membrane-bound organelles.
- Therefore, Thallophyta is also not the answer.

6. **Analyzing Prokaryota**:
- Prokaryotic cells are unicellular and lack a true nucleus.
- They do not have membrane-bound organelles, meaning they do not possess intracellular membranes.
- This makes Prokaryota the correct answer.

7. **Conclusion**: Based on the analysis, the type of cell that lacks intracellular membranes is Prokaryota.

### Final Answer:
The correct answer is **Prokaryota**.
