Which one is wrongly matched?

Options

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

Answer

To determine which option is wrongly matched, we need to analyze each pairing provided in the question.

### Step-by-Step Solution:

1. **Identify the First Option: Uniflagellated Gametes and Polysiphonia**
- Polysiphonia is a type of red algae.
- Red algae typically do not have flagellated gametes; they are mostly non-motile.
- Therefore, this pairing is incorrect.

2. **Identify the Second Option: Biflagellate and Juice Pores**
- Juice pores are associated with brown algae, which have biflagellate gametes (two flagella).
- This pairing is correct.

3. **Identify the Third Option: Brown Algae and Gemma**
- Gemmae are asexual reproductive structures found in liverworts, which are part of bryophytes, not in brown algae.
- This pairing is incorrect.

4. **Identify the Fourth Option: Unicellular Organism and Cholera**
- Cholera is caused by the bacterium Vibrio cholerae, which is indeed a unicellular organism.
- This pairing is correct.

### Conclusion:
The first option, "Uniflagellated Gametes and Polysiphonia," is wrongly matched because Polysiphonia does not have uniflagellated gametes; it is primarily non-motile.

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