The main function of lysosome is

Options

A. Sexual reproduction
B. Extracellular digestion
C. Intracellular digestion
D. Both (2) and (3)

Answer

**Step-by-Step Solution:**

1. **Understanding Lysosomes**: Lysosomes are membrane-bound organelles found in eukaryotic cells. They contain various enzymes that are crucial for breaking down different types of biomolecules.

2. **Formation of Lysosomes**: Lysosomes are formed by the Golgi apparatus, which packages enzymes into vesicles that become lysosomes.

3. **Functions of Lysosomes**: The primary function of lysosomes is to digest and break down cellular waste, damaged organelles, and foreign materials. This process is essential for maintaining cellular health.

4. **Types of Digestion**: Lysosomes are involved in two types of digestion:
- **Intracellular Digestion**: This refers to the digestion of materials that are already inside the cell, such as worn-out organelles (autophagy).
- **Extracellular Digestion**: This involves the breakdown of materials that are outside the cell, which can be brought into the cell through processes like endocytosis.

5. **Conclusion**: Since lysosomes are responsible for both extracellular and intracellular digestion, the correct answer to the question is that the main function of lysosomes includes both types of digestion.

6. **Final Answer**: The main function of lysosomes is both extracellular and intracellular digestion (Option 4).
