Which one is wrongly matched?

Options

A. Gemma cups - Marchantia
B. Biflagellate zoospores - Brown algae
C. Uniflagellate gametes - Polysiphonia
D. Unicellular organism - Chlorella

Answer

To determine which match is wrongly matched in the given options, we will analyze each of the pairs mentioned in the question step by step.

### Step-by-Step Solution:

1. **Identify the First Pair: Gemma Cups and Marchantia**
- Marchantia is a well-known example of liverworts, which are classified under bryophytes.
- Gemma cups are specialized structures found in liverworts that contain gemmae, which are asexual reproductive structures.
- **Conclusion**: This pair is correctly matched.

2. **Identify the Second Pair: Brown Algae and Biflagellated Gametes**
- Brown algae are known to have gametes that are biflagellated, meaning they possess two flagella.
- This is a characteristic feature of many brown algae species.
- **Conclusion**: This pair is correctly matched.

3. **Identify the Third Pair: Polysiphonia and Uniflagellated Gametes**
- Polysiphonia is a type of red algae.
- Red algae typically do not have flagella in their gametes; they are known for having non-motile gametes.
- Therefore, stating that Polysiphonia has uniflagellated gametes is incorrect.
- **Conclusion**: This pair is wrongly matched.

4. **Identify the Fourth Pair: Cholera and Unicellular Organism**
- Cholera is caused by the bacterium Vibrio cholerae, which is indeed a unicellular organism.
- This is a correct classification.
- **Conclusion**: This pair is correctly matched.

### Final Answer:
The wrongly matched pair is **Polysiphonia and Uniflagellated Gametes**.
