Which is wrongly matched ?

Options

A. Sargassum - chl c
B. Basidiomycetes - puffballs
C. Nostoc - water bloom
D. Spirogyra – flagellated gametes

Explanation

To determine which option is wrongly matched, let's analyze each option step by step:

1. **Option 1: Sargassum and Chlorophyll C**
- Sargassum is a type of brown algae, and brown algae contain chlorophyll A and chlorophyll C, along with other pigments like fucoxanthin that give them their characteristic brown color. Therefore, this match is correct.

2. **Option 2: Basidiomycetes and Puffballs**
- Basidiomycetes are a group of fungi that reproduce sexually through specialized structures called basidia. Puffballs are indeed a type of fungi that belong to this group. Therefore, this match is also correct.

3. **Option 3: Nostoc and Water Bloom**
- Nostoc is a cyanobacterium that can cause water blooms when it grows in large quantities. This is a well-known phenomenon in aquatic environments. Thus, this match is correct as well.

4. **Option 4: Spirogyra and Flagellated Gametes**
- Spirogyra is a green algae known for its spiral chloroplasts. The gametes of Spirogyra are non-motile and do not have flagella. Therefore, stating that Spirogyra has flagellated gametes is incorrect. This is the wrongly matched option.

**Conclusion:**
The wrongly matched option is **Option 4: Spirogyra and Flagellated Gametes**.
