Which of the following cell organelles are non membranous and found in both prokaryotic and eukaryotic cells?

Options

A. Lysosomes
B. Microbodies
C. Ribosomes
D. Vacuoles

Answer

To determine which cell organelles are non-membranous and found in both prokaryotic and eukaryotic cells, we will analyze each of the given options one by one:

### Step-by-Step Solution:

1. **Understanding Non-Membranous Organelles**:
- Non-membranous organelles are those that do not have a lipid bilayer surrounding them. They are not enclosed by membranes, unlike membrane-bound organelles.

2. **Evaluating the Options**:
- **Option 1: Lysosomes**:
- Lysosomes are membrane-bound organelles that contain hydrolytic enzymes for digestion. They are found only in eukaryotic cells.
- **Conclusion**: Not non-membranous and not found in prokaryotes.

- **Option 2: Microbodies**:
- Microbodies (such as peroxisomes) are also membrane-bound organelles involved in various metabolic processes. They are found in eukaryotic cells and some fungi but are not present in prokaryotic cells.
- **Conclusion**: Not non-membranous and not found in prokaryotes.

- **Option 3: Ribosomes**:
- Ribosomes are non-membranous organelles that are essential for protein synthesis. They are found in both prokaryotic (70S ribosomes) and eukaryotic (80S ribosomes) cells.
- **Conclusion**: Non-membranous and found in both prokaryotic and eukaryotic cells.

- **Option 4: Vacuoles**:
- Vacuoles are membrane-bound organelles that store substances and help maintain turgor pressure in plant cells. They are present in eukaryotic cells but absent in prokaryotic cells.
- **Conclusion**: Not non-membranous and not found in prokaryotes.

3. **Final Answer**:
- The only organelle that is non-membranous and found in both prokaryotic and eukaryotic cells is **Ribosomes** (Option 3).
