Which of the following is not characteristic of a eukaryotic plant cell?

Options

A. Ribosomes associated with endoplasmic reticulum
B. Dictyosomes associated with Golgi bodies
C. Cristae inside of mitochondria
D. Thylakoids inside of chloroplasts

Explanation

To determine which of the following options is not characteristic of a eukaryotic plant cell, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze the First Option: Ribosomes associated with endoplasmic reticulum**
- In eukaryotic plant cells, ribosomes can be found both free in the cytoplasm and attached to the endoplasmic reticulum (ER). The ER with attached ribosomes is known as Rough Endoplasmic Reticulum (RER).
- **Conclusion**: This option is a characteristic of eukaryotic plant cells.

2. **Analyze the Second Option: Dictyosomes associated with Golgi bodies**
- Dictyosomes are actually another name for Golgi bodies. Therefore, saying that Dictyosomes are associated with Golgi bodies is incorrect, as they are essentially the same structure.
- **Conclusion**: This option is not a characteristic of eukaryotic plant cells.

3. **Analyze the Third Option: Cristae inside the mitochondria**
- Cristae are the inner membrane folds found within mitochondria. They increase the surface area for biochemical reactions, such as ATP production.
- **Conclusion**: This option is a characteristic of eukaryotic plant cells.

4. **Analyze the Fourth Option: Thylakoids inside chloroplasts**
- Thylakoids are membrane-bound structures found within chloroplasts, where the light-dependent reactions of photosynthesis occur. They are indeed a characteristic of chloroplasts in eukaryotic plant cells.
- **Conclusion**: This option is a characteristic of eukaryotic plant cells.

### Final Conclusion:
Based on the analysis, the option that is not characteristic of a eukaryotic plant cell is **Dictyosomes associated with Golgi bodies**.
