Which is incorrect in relation to lysosome

Options

A. They contain acid hydrolases
B. They are autophagic
C. They can digest proteins, nucleic acids, lipids and polysaccharides
D. They are monomorphic

Answer

### Step-by-Step Text Solution:

1. **Understanding Lysosomes**: Lysosomes are membrane-bound organelles found primarily in animal cells (eukaryotic cells) that contain digestive enzymes.

2. **Analyzing the Statements**:
- **Statement 1**: "They contain acid hydrolases."
- This statement is **correct**. Lysosomes contain acid hydrolases that help in the digestion of various biomolecules.

- **Statement 2**: "They are autophagic."
- This statement is also **correct**. Lysosomes can engulf and digest their own cellular components, which is a process known as autophagy.

- **Statement 3**: "They can digest proteins, nucleic acids, lipids, and polysaccharides."
- This statement is **correct** as well. Lysosomes contain various enzymes (proteases, nucleases, lipases) that enable them to digest these biomolecules.

- **Statement 4**: "They are monomorphic."
- This statement is **incorrect**. Lysosomes are not monomorphic; they are pleomorphic, meaning they can exist in various forms depending on their function (e.g., primary lysosomes, secondary lysosomes, and residual bodies).

3. **Conclusion**: The incorrect statement in relation to lysosomes is that they are monomorphic. Therefore, the answer is **"They are monomorphic."**
