Identify the cell organelles present only in animals cells

Options

A. Nucleus
B. Centrosomes
C. Plastids
D. Lysosomes

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks us to identify the cell organelles that are present only in animal cells. This means we need to differentiate between organelles found in both plant and animal cells and those that are exclusive to animal cells.

2. **Analyzing the Options**:
- **Option 1: Nucleus**: The nucleus is present in both plant and animal cells. It controls cellular activities, so this option is incorrect.
- **Option 2: Centrosome**: The centrosome is a structure found only in animal cells. It consists of two centrioles and plays a crucial role in cell division. This option is correct.
- **Option 3: Plastids**: Plastids are found only in plant cells and are involved in processes like photosynthesis and storage. Therefore, this option is incorrect.
- **Option 4: Lysosomes**: While lysosomes are more common in animal cells, they can also be found in some plant cells, though less frequently. However, they are primarily associated with animal cells, but they are not exclusively found there. This option is somewhat misleading.

3. **Conclusion**: After analyzing the options, the only organelle that is exclusively found in animal cells is the **Centrosome**.

**Final Answer**: The cell organelle present only in animal cells is the **Centrosome**.
