Certain golgain vesicles which are budded- out from the trans - face contains acid hydrolases. Such vesicles are better termed as

Options

A. Heterophagosomes
B. Microsomes
C. Phragmosomes
D. Primary lysosomes

Answer

To solve the question regarding the Golgi vesicles that contain acid hydrolases, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**:
- The Golgi apparatus is an organelle involved in modifying, sorting, and packaging proteins and lipids received from the endoplasmic reticulum (ER). It has two main faces: the cis face (receiving side) and the trans face (shipping side).

**Hint**: Remember the structure and function of the Golgi apparatus, focusing on its two faces.

2. **Identifying the Vesicles**:
- The question specifies that the vesicles budded from the trans face of the Golgi apparatus contain acid hydrolases. Acid hydrolases are enzymes that function optimally at acidic pH and are typically involved in breaking down various biomolecules.

**Hint**: Think about the types of enzymes that are associated with lysosomes and their functions.

3. **Function of Acid Hydrolases**:
- Acid hydrolases are characteristic of lysosomes, which are organelles responsible for the degradation of waste materials and cellular debris. The vesicles containing these enzymes are crucial for the lysosomal function.

**Hint**: Recall the role of lysosomes in cellular digestion and waste management.

4. **Naming the Vesicles**:
- The vesicles that contain acid hydrolases and are formed from the Golgi apparatus are specifically referred to as primary lysosomes. These vesicles will eventually fuse with other vesicles to form secondary lysosomes, where the degradation of materials occurs.

**Hint**: Consider the terminology related to lysosomes and their stages of development.

5. **Conclusion**:
- Based on the information about the Golgi apparatus and the function of acid hydrolases, the correct term for the vesicles that bud from the trans face and contain these enzymes is "primary lysosomes."

### Final Answer:
The vesicles are better termed as **Primary Lysosomes**.
