Assertion. Lysosomes are organelle in eukaryotic cell that contains digestive enzymes to digest macromolecules.
Reason. Lysosomes are also called phagolysosomes or heterophagosomes or digestive vacuoles.

Options

A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
B. Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
C. Assertion is true but Reason is false
D. Both Assertion and Reason are false

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states: "Lysosomes are organelles in eukaryotic cells that contain digestive enzymes to digest macromolecules."

- **Explanation**: Lysosomes are indeed organelles found in eukaryotic cells. They are membrane-bound structures that contain hydrolytic enzymes capable of breaking down various macromolecules, including proteins, lipids, carbohydrates, and nucleic acids. This statement is true.

### Step 2: Analyze the Reason
The reason states: "Lysosomes are also called phagolysosomes or heterophagosomes or digestive vacuoles."

- **Explanation**: While lysosomes are involved in the digestion of materials within the cell, they are not directly referred to as phagolysosomes or heterophagosomes. Phagolysosomes are formed when a lysosome fuses with a phagosome (a food vacuole containing engulfed material). The term "digestive vacuoles" can refer to lysosomes, but it is more specific to the context of phagocytosis. This statement is also true, but it does not accurately explain why lysosomes are called digestive organelles.

### Step 3: Conclusion
Both the assertion and the reason are true statements, but the reason does not correctly explain the assertion. Therefore, the correct answer is that both statements are true, but the reason is not the correct explanation of the assertion.

### Final Answer
The correct option is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
