Where are proteins synthesised inside the cell?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where proteins are synthesized inside the cell. This requires knowledge of cell organelles and their functions.

2. **Identifying the Organelle**: The primary site of protein synthesis in the cell is the ribosome. Ribosomes are essential for translating genetic information into proteins.

3. **Function of Ribosomes**: Ribosomes are often referred to as the "protein factories" of the cell because they are responsible for assembling amino acids into proteins based on the instructions provided by messenger RNA (mRNA).
