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, we will analyze each option one by one:

1. **Sargassum is matched with chlorophyll C**:
- Sargassum is a type of brown algae. Brown algae contain chlorophyll A and chlorophyll C, along with other pigments such as carotenoids and fucoxanthin.
- Therefore, this option is **correctly matched**.

2. **Basidiomycetes are matched with puffballs**:
- Basidiomycetes include various fungi, and puffballs are indeed a type of Basidiomycete. Other examples include mushrooms and bracket fungi.
- Hence, this option is also **correctly matched**.

3. **Nostoc is matched with water bloom**:
- Nostoc is a genus of cyanobacteria that can grow in large quantities, leading to water blooms. This is a well-known characteristic of Nostoc.
- Thus, this option is **correctly matched**.

4. **Spirogyra is matched with flagellated gametes**:
- Spirogyra is a green algae, and its gametes are non-flagellated (non-motile). Instead, they move via a process called conjugation, which is not associated with flagella.
- Therefore, this option is **incorrectly matched**.

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

**Answer**: Option 4 (Spirogyra with flagellated gametes).
