Animal cells do not possess

Options

A. Plasmodesmata
B. Centriole
C. 80 S ribosomes
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which structure is not present in animal cells. The options given are plasmodesmata, centriole, ribosome, and all of the above.

2. **Analyzing Each Option**:
- **Plasmodesmata**: These are channels that allow communication and transport between plant cells. They are not found in animal cells, as animal cells have different mechanisms for cell communication.
- **Centriole**: Centrioles are present in animal cells and are involved in cell division, specifically in the formation of spindle fibers.
- **Ribosome**: Ribosomes are present in both prokaryotic and eukaryotic cells, including animal cells. They are essential for protein synthesis.

3. **Eliminating Incorrect Options**:
- Since centrioles and ribosomes are present in animal cells, we can eliminate those options.
- This leaves us with plasmodesmata as the only structure that is not found in animal cells.

4. **Conclusion**: The correct answer is that animal cells do not possess plasmodesmata.

**Final Answer**: Animal cells do not possess plasmodesmata.
