Suicidal bags of a cell were discovered by

Options

A. De Duve
B. Fontana
C. Palade
D. Golgi

Answer

To answer the question "Suicidal bags of a cell were discovered by," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Suicidal Bags":**
- The term "suicidal bags" refers to lysosomes, which are organelles in the cell that contain hydrolytic enzymes. These enzymes help in breaking down waste materials and cellular debris.

2. **Function of Lysosomes:**
- Lysosomes are responsible for digesting worn-out organelles, food particles, and engulfing viruses or bacteria. They play a crucial role in cellular waste disposal and recycling.

3. **Identify the Scientist:**
- The question asks for the scientist who discovered these lysosomes. The correct answer is D2F (De Duve), who identified lysosomes in 1955.

4. **Eliminate Incorrect Options:**
- **Fontana:** Discovered the living part of the cell (cytoplasm), not lysosomes.
- **Palade:** Known for discovering ribosomes, referred to as Palade particles.
- **Golgi:** Discovered the Golgi apparatus, not lysosomes.

5. **Conclusion:**
- Based on the information, the correct answer to the question is **D2F**.

### Final Answer:
**D2F** discovered the suicidal bags of a cell, known as lysosomes, in 1955.
