Which one of the following is wrongly matched?

Options

A. Nostoc-Water blooms
B. Spirogyra-Motile gametes
C. Sargassum-Chlorophyllc
D. Basidiomycetes-Puffballs

Answer

To determine which of the following options is wrongly matched, we need to analyze each option carefully:

1. **No Stock Water Bloom**: This option refers to the phenomenon of water blooms in algae, which is indeed associated with the genus Microcystis. The term "No Stock" seems to be a misrepresentation or a typographical error, but it is generally accepted that Microcystis can cause water blooms. Therefore, this option is correctly matched.

2. **Espirogyra Motile Gametes**: Espirogyra is a genus of green algae (Chlorophyceae) known for its filamentous structure. Importantly, Espirogyra does not produce motile gametes; instead, it reproduces sexually through non-motile gametes (conjugation). Thus, this option is wrongly matched.

3. **Sargassum Chlorophyll C**: Sargassum is a genus of brown algae (Phaeophyceae) that contains chlorophyll A and C. This option is correctly matched, as Sargassum does indeed contain chlorophyll C.

4. **Bacidiomycetes Puff Balls**: Puff balls are indeed the fruiting bodies of certain fungi, and they belong to the class Basidiomycetes. This option is also correctly matched.

After analyzing all the options, we conclude that the wrongly matched option is:

**Option 2: Espirogyra Motile Gametes.**
