Smallest cell organelle discovered by Palade (1953) is

Options

A. Lysosome
B. Centrosome
C. Ribosome
D. Golgibody

Answer

**Step-by-Step Solution:**

1. **Identify the Discoverer and Year**: The question asks for the smallest cell organelle discovered by Palade in 1953. This indicates we need to focus on the contributions of scientist George E. Palade.

2. **Recognize the Discovery**: In 1953, George E. Palade discovered small dense particles within the cell, which were initially referred to as "Palade particles."

3. **Name the Organelle**: These particles were later identified as ribosomes. Ribosomes are the smallest organelles in the cell and play a crucial role in protein synthesis.

4. **Characteristics of Ribosomes**: Ribosomes are unique because they are found in both prokaryotic and eukaryotic cells. They do not have a surrounding membrane, which distinguishes them from many other organelles.

5. **Function of Ribosomes**: The primary function of ribosomes is to synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

6. **Conclusion**: Therefore, the smallest cell organelle discovered by Palade in 1953 is the ribosome.

**Final Answer**: Ribosomes
