Find the incorrect match

Options

A. Isogametes-Cladophora
B. Isogametes-Fucus
C. Heterogametes-Homo sapiens
D. Heterogametes-Fucus

Answer

To find the incorrect match among the given pairs of gametes and their corresponding organisms, we need to analyze each match based on the definitions of isogametes and heterogametes.

### Step-by-Step Solution:

1. **Identify Isogametes and Heterogametes:**
- **Isogametes**: These are gametes that are morphologically similar and cannot be distinguished as male or female.
- **Heterogametes**: These are gametes that are morphologically different, allowing for easy identification of male and female gametes.

2. **Evaluate the First Match: Isogametes with Cladophora**
- Cladophora is a green algae that produces isogametes. Both gametes are flagellated and look identical.
- **Conclusion**: This match is **correct**.

3. **Evaluate the Second Match: Isogametes with Fucus**
- Fucus is a brown algae that produces heterogametes. The male and female gametes are different in size and motility (male gametes are small and motile, while female gametes are larger and non-motile).
- **Conclusion**: This match is **incorrect**.

4. **Evaluate the Third Match: Heterogametes with Homo sapiens**
- Humans (Homo sapiens) produce heterogametes. Male gametes (sperm) are small and motile, while female gametes (ova) are larger and non-motile.
- **Conclusion**: This match is **correct**.

5. **Evaluate the Fourth Match: Heterogametes with Fucus**
- As previously mentioned, Fucus produces heterogametes, which can be easily distinguished as male and female.
- **Conclusion**: This match is **correct**.

### Final Conclusion:
The incorrect match is **Isogametes with Fucus**.
