Which one is incorrect with reference to lysosome ?

Options

A. They are filled with acid hydrolase and other enzymes.
B. They are monomorphic and uniform in structure and function.
C. They may be autophagic.
D. They can digest proteins, nucleic acids, lipids and polysaccharides

Answer

To determine which statement about lysosomes is incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Lysosomes**:
- Lysosomes are membrane-bound organelles found in eukaryotic cells.
- They contain hydrolytic enzymes that function best at acidic pH.

2. **Analyzing the First Statement**:
- The first statement claims that lysosomes are filled with acid hydrolases and other enzymes.
- This statement is correct because lysosomes indeed contain various hydrolytic enzymes such as carbohydrases, lipases, proteases, and nucleases.

3. **Analyzing the Second Statement**:
- The second statement claims that lysosomes are monomorphic.
- This statement is incorrect. Lysosomes are polymorphic, meaning they can exist in different forms (primary, secondary, and tertiary lysosomes) and are not uniform in structure.

4. **Analyzing the Third Statement**:
- The third statement states that lysosomes are autophagic.
- This statement is correct. Lysosomes are involved in autophagy, which is the process of self-digestion, breaking down cellular components and organelles.

5. **Conclusion**:
- The incorrect statement regarding lysosomes is that they are monomorphic (the second statement). Therefore, the answer to the question is that lysosomes are not monomorphic; they are polymorphic.

### Final Answer:
The incorrect statement with reference to lysosomes is: "It is monomorphic."
