Which type of ribosomes are present in prokaryotic cells and eukaryotic cells ? Give their two sub-units also.

Explanation

### Step-by-Step Solution:

1. **Understanding Ribosomes**: Ribosomes are essential organelles responsible for protein synthesis in both prokaryotic and eukaryotic cells. They are not membrane-bound, meaning they do not have a surrounding membrane.

2. **Ribosomes in Prokaryotic Cells**: In prokaryotic cells, the type of ribosomes present is known as **70S ribosomes**. The "S" stands for Svedberg units, which measure the rate of sedimentation during centrifugation, reflecting the size and density of the ribosome.

3. **Subunits of Prokaryotic Ribosomes**: The 70S ribosomes in prokaryotes are made up of two subunits:
- **Large Subunit**: 50S
