Ribosomes are found

Options

A. only in the nucleus
B. in the cytoplasm
C. only in eukaryotic cells
D. both (b) and (c )

Explanation

**Step-by-Step Solution:**

1. **Understanding Ribosomes**: Ribosomes are small, dense spherical particles that play a crucial role in protein synthesis. They are made up of ribosomal RNA (rRNA) and proteins.

2. **Location of Ribosomes**: Ribosomes can be found in two primary locations within a cell:
- **Free Ribosomes**: These are located freely in the cytoplasm. They synthesize proteins that function within the cytosol.
- **Bound Ribosomes**: These are attached to the rough endoplasmic reticulum (RER). They synthesize proteins that are usually secreted from the cell or incorporated into the cell's membranes.
