The cell organelle in which hydrolytic enzymes are stored is:

Options

A. Plastid
B. Mitochondria
C. Centrosome
D. Lysosome

Explanation

To solve the question about which cell organelle stores hydrolytic enzymes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hydrolytic Enzymes**: Hydrolytic enzymes are biological catalysts that facilitate the breakdown of complex molecules into simpler ones through hydrolysis. They play a crucial role in digestion and cellular metabolism.

2. **Identify Cell Organelles**: Familiarize yourself with various cell organelles and their functions. Key organelles include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes.

3. **Focus on Lysosomes**: Among the organelles, lysosomes are known for containing hydrolytic enzymes. They are membrane-bound organelles that contain digestive enzymes capable of breaking down various biomolecules, including proteins, nucleic acids, carbohydrates, and lipids.

4. **Confirm the Function of Lysosomes**: Lysosomes are often referred to as the "digestive system" of the cell because they help degrade waste materials and cellular debris. This function is primarily due to the presence of hydrolytic enzymes within them.

5. **Conclude the Answer**: Based on the understanding that lysosomes store hydrolytic enzymes, we conclude that the correct answer to the question is lysosomes.

### Final Answer:
The cell organelle in which hydrolytic enzymes are stored is **lysosomes**.
