Which of the following features is commen to prokaryotes any many eukaryotes ?

Options

A. Chromatin material present
B. Cell wall present
C. Nuclear membrane present
D. Membrane-bound subcellular organells present

Explanation

To determine which feature is common to prokaryotes and many eukaryotes, we can analyze the options provided. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Prokaryotes and Eukaryotes
- Prokaryotes are primitive cells, simpler in structure, and do not have a nucleus or membrane-bound organelles.
- Eukaryotes are more complex, with a defined nucleus and various membrane-bound organelles.

**Hint:** Remember the basic structural differences between prokaryotic and eukaryotic cells.

### Step 2: Analyze the Options
1. **Chromatin Material Present**
- Chromatin is found only in eukaryotic cells. Prokaryotes do not have chromatin.
- **Conclusion:** This feature is not common.

2. **Cell Wall Present**
- Both prokaryotic cells and many eukaryotic cells (like plants, fungi, and some protists) have a cell wall.
- **Conclusion:** This feature is common.

3. **Nuclear Membrane**
- The nuclear membrane is present only in eukaryotic cells and absent in prokaryotic cells.
- **Conclusion:** This feature is not common.

4. **Membrane Bound Subcellular Organelles**
- Membrane-bound organelles are present in eukaryotes but absent in prokaryotes.
- **Conclusion:** This feature is not common.

### Step 3: Identify the Common Feature
- After analyzing all the options, the only feature that is common to both prokaryotes and many eukaryotes is the presence of a **cell wall**.

### Final Answer
The correct answer is **Cell Wall Present**.
