B. i. Mesophyll, ii. Ribosomal protein
C. iii. Transfer RNA, iv. Chiasmata
D. iv . Synapsis , i. Cis

Answer

To solve the question, we need to fill in the blanks for the four statements provided. Let's analyze each statement step by step:

### Step 1: Analyze Statement i
**Statement:** Materials to be packaged in the form of vesicles from the ER fuse with the ……face of the Golgi apparatus.

- The Golgi apparatus has two distinct faces: the cis face (the side facing the endoplasmic reticulum) and the trans face (the side facing away from the endoplasmic reticulum).
- Vesicles from the ER fuse with the **cis face** of the Golgi apparatus.

**Fill in the blank:** cis

### Step 2: Analyze Statement ii
**Statement:** Majority of the chloroplasts of the green plants are found in the ..........cells of leaves.

- Chloroplasts are primarily located in the mesophyll cells of leaves, which are responsible for photosynthesis.

**Fill in the blank:** mesophyll

### Step 3: Analyze Statement iii
**Statement:** The nucleolus is a site for active ...........synthesis.

- The nucleolus is known for synthesizing ribosomal RNA (rRNA), which is essential for ribosome formation.

**Fill in the blank:** rRNA

### Step 4: Analyze Statement iv
**Statement:** During zygotene, chromosomes start pairing together and this process of association is called ............ .

- The process of chromosome pairing during zygotene is known as **synapsis**.

**Fill in the blank:** synapsis

### Summary of Answers
1. **Statement i:** cis
2. **Statement ii:** mesophyll
3. **Statement iii:** rRNA
4. **Statement iv:** synapsis

### Final Answer
The correct option that fills up the blanks in any of the two statements is:
- **cis** for Statement i
- **mesophyll** for Statement ii
- **rRNA** for Statement iii
- **synapsis** for Statement iv
