Answer

To solve the question "Animal cells are different from plant cells in lack of," we will analyze the options provided and determine which structures are absent in animal cells compared to plant cells.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Cell wall
- B) Plastids
- C) Nucleus
- D) 1 & 2 (which means both Cell wall and Plastids)

2. **Understand Cell Types**:
- Both animal cells and plant cells are eukaryotic cells, meaning they have a defined nucleus and organelles.

3. **Examine Plant Cells**:
- Plant cells have a **cell wall**, which provides structure and protection.
- Plant cells contain **plastids** (like chloroplasts), which are involved in photosynthesis and storage of food.

4. **Examine Animal Cells**:
- Animal cells do **not** have a cell wall; they have a flexible plasma membrane instead.
- Animal cells do **not** have plastids; they cannot perform photosynthesis and are heterotrophic, meaning they rely on other organisms for food.

5. **Nucleus Presence**:
- Both animal and plant cells have a **nucleus**. It is essential for controlling cell activities and contains genetic material.

6. **Conclusion**:
- Since both the cell wall and plastids are absent in animal cells, the correct answer is **option D (1 & 2)**, indicating that animal cells lack both the cell wall and plastids.

### Final Answer:
The answer is **1 & 2 (Cell wall and Plastids)**.
