Material to be packaged in the form of vesicles from the ER fuse with (A)____face of Golgi apparatus and move towards the (B)____ face.

Answer

To answer the question regarding the Golgi apparatus and the endoplasmic reticulum (ER), we need to fill in the blanks for the following statement: "Material to be packaged in the form of vesicles from the ER fuse with (A)____ face of Golgi apparatus and move towards the (B)____ face."

### Step-by-Step Solution:

1. **Identify the Role of the Endoplasmic Reticulum (ER)**:
- The endoplasmic reticulum is responsible for synthesizing various compounds, such as proteins and lipids. These compounds need to be modified and packaged for transport to their final destinations.

2. **Understanding Vesicle Formation**:
- After synthesis, the compounds are packaged into vesicles. These vesicles are small membrane-bound sacs that transport materials within the cell.

3. **Vesicle Fusion with the Golgi Apparatus**:
- The vesicles containing the synthesized materials from the ER will fuse with a specific side of the Golgi apparatus. This side is known as the "cis face" of the Golgi apparatus.

4. **Movement Through the Golgi Apparatus**:
- Once the vesicles fuse with the cis face, the materials undergo further modifications and processing as they move through the Golgi apparatus.

5. **Exit from the Golgi Apparatus**:
- After processing, the materials are packaged into new vesicles that bud off from the opposite side of the Golgi apparatus, known as the "trans face."

### Final Answers:
- (A) **cis**
- (B) **trans**

### Summary:
The material to be packaged in the form of vesicles from the ER fuses with the **cis face** of the Golgi apparatus and moves towards the **trans face**.
