Which of these is wrongly matched

Options

A. 70 S ribosomes -Prokaryotes
B. 80 S ribosomes-Eukaryotes
C. Axoneme -Cilia
D. Thylakoids-Chlorophyll

Answer

To determine which of the options is wrongly matched, let's analyze each option step by step.

### Step 1: Analyze Option A - 70S ribosomes in Prokaryotes
- **Explanation**: 70S ribosomes are indeed found in prokaryotic cells. They are smaller than the 80S ribosomes found in eukaryotic cells.
- **Conclusion**: This option is correctly matched.

### Step 2: Analyze Option B - 80S ribosomes in Eukaryotes
- **Explanation**: 80S ribosomes are characteristic of eukaryotic cells. They are larger and more complex than 70S ribosomes.
- **Conclusion**: This option is also correctly matched.

### Step 3: Analyze Option C - Exoneme in Cilia
- **Explanation**: The exoneme is a structural component of cilia and flagella, consisting of a specific arrangement of microtubules (the "9+2" arrangement).
- **Conclusion**: This option is correctly matched.

### Step 4: Analyze Option D - Thylakoid in Chlorophyll
- **Explanation**: Thylakoids are membrane-bound structures within chloroplasts where chlorophyll is located. However, the statement "thylakoid chlorophyll" implies that chlorophyll is a part of thylakoids, which is misleading. Chlorophyll is found in the thylakoid membranes, not as a component of thylakoids themselves.
- **Conclusion**: This option is incorrectly matched.

### Final Answer
The wrongly matched option is **D. Thylakoid Chlorophyll**.
