Which one of the following is wrongly matched ?

Options

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

Answer

To determine which of the following options is wrongly matched, we will analyze each option provided in the question.

**Step 1: Analyze the first option - Nostoc and water blooms.**
- Nostoc is a type of cyanobacteria that can cause water blooms, which is a rapid increase in algal population in water bodies. This statement is correct.

**Step 2: Analyze the second option - Spirogyra and motile gametes.**
- Spirogyra is a green alga that reproduces sexually through a process called conjugation. It produces non-motile gametes, not motile ones. Therefore, this option is wrongly matched.

**Step 3: Analyze the third option - Sargassum and chlorophyll C.**
- Sargassum is a brown alga that contains chlorophyll A and chlorophyll C. This statement is correct.

**Step 4: Analyze the fourth option - Basidiomycetes and puffballs.**
- Basidiomycetes is a group of fungi that includes puffballs. They produce basidocarps, which can resemble puffballs. This statement is also correct.

**Conclusion:**
The only wrongly matched option is Spirogyra with motile gametes, as Spirogyra actually has non-motile gametes.

**Final Answer:**
The wrongly matched option is Spirogyra - motile gametes.
