All eukaryotic cells are not identical

Answer

### Step-by-Step Solution

1. **Understanding Eukaryotic Cells**:
- Eukaryotic cells are complex cells that contain membrane-bound organelles and a well-defined nucleus. They are found in multicellular organisms, including plants, animals, fungi, and protists.

2. **Identifying the Differences**:
- While all eukaryotic cells share certain characteristics, they are not identical. This can be demonstrated by comparing plant cells and animal cells, both of which are eukaryotic.

3. **Comparing Plant and Animal Cells**:
- **Cell Wall**: Plant cells have a rigid cell wall made of cellulose, which provides structure and protection. In contrast, animal cells do not have a cell wall; they only have a flexible plasma membrane.
- **Vacuoles**: Plant cells typically contain a large central vacuole that stores water, nutrients, and waste products. Animal cells may have small vacuoles, but they are not as prominent or as large as those in plant cells.
- **Plastids**: Plant cells contain plastids (like chloroplasts) that are involved in photosynthesis and storage of starch. Animal cells do not have plastids.
- **Centrioles**: Animal cells contain centrioles, which are involved in cell division. Plant cells generally do not have centrioles.

4. **Conclusion**:
- Due to these differences in structure and function, it is accurate to state that all eukaryotic cells are not identical. The variations among different types of eukaryotic cells (like plant and animal cells) illustrate the diversity within this category of cells.
