These types of vacuole contain hydrolases

Options

A. Sap
B. Contractile
C. Food
D. Air

Answer

**Step-by-Step Solution:**

1. **Understanding Vacuoles**: Vacuoles are membrane-bound organelles found in cells, primarily in plant and fungal cells, and they serve various functions including storage, waste disposal, and maintaining turgor pressure.

2. **Identifying Hydrolases**: Hydrolases are a type of enzyme that catalyze the hydrolysis of chemical bonds. They can be classified into different types based on the substrate they act on, such as:
- Carbohydrases (break down carbohydrates)
- Lipases (break down lipids)
- Proteases (break down proteins)
- Nucleases (break down nucleic acids)

3. **Relating Hydrolases to Vacuoles**: Since hydrolases are involved in breaking down food molecules, they are typically found in vacuoles that are responsible for digestion and storage of nutrients.

4. **Identifying the Correct Type of Vacuole**: The vacuole that contains hydrolases is known as the **food vacuole**. This type of vacuole is involved in the digestion of food particles within the cell.

5. **Excluding Other Types of Vacuoles**:
- **Sap Vacuole**: Primarily involved in storage of nutrients and waste products, not specifically for digestion.
- **Contractile Vacuole**: Found in some protozoans like amoeba, it helps in expelling excess water and is not involved in digestion.
- **Gas Vacuole**: Found in certain bacteria, it helps in buoyancy and does not contain hydrolases.

6. **Conclusion**: Therefore, the type of vacuole that contains hydrolases is the **food vacuole**.

**Final Answer**: Food vacuole.
