are called as suicidal bags.

Options

A. Gas vacuoles
B. Autophagic vacuoles
C. Food vacuoles
D. Contractile vacuoles

Answer

To solve the question "_____ are called as suicidal bags," we need to identify the organelle that is commonly referred to as "suicidal bags" due to its function in the cell.

### Step-by-Step Solution:

1. **Understanding the Term "Suicidal Bags":**
- The term "suicidal bags" refers to organelles that can lead to the death of a cell through a process called autolysis. This is where the organelle helps in breaking down the cell's own components.

2. **Identifying the Organelle:**
- The organelle that is primarily responsible for this function is the lysosome. Lysosomes contain digestive enzymes that can break down waste materials and cellular debris. When a cell is damaged or no longer needed, lysosomes can release these enzymes to digest the cell itself, leading to cell death.

3. **Evaluating the Options:**
- **Gas Vacuole:** This organelle is involved in buoyancy control in some bacteria and does not relate to cell death.
- **Autophagic Vacuole:** This term suggests a vacuole that eats itself, which is somewhat related but not the commonly accepted term for "suicidal bags."
- **Food Vacuole:** This vacuole is involved in the digestion of food particles and does not relate to self-destruction.
- **Contractile Vacuoles:** These are involved in osmoregulation and do not have a role in cell death.

4. **Conclusion:**
- The correct answer to fill in the blank is "lysosomes." Thus, the complete statement would be: "Lysosomes are called as suicidal bags."

### Final Answer:
**Lysosomes are called as suicidal bags.**
