Algae having heterogametes are

Options

A. Funaria and Pteris
B. liver worts
C. Chara and Fucus
D. Chara and Marchantia

Answer

To determine which algae have heterogametes, we need to understand the concept of heterogametes and how they differ from isogametes.

### Step-by-step Solution:

1. **Understanding Heterogametes**:
- Heterogametes are gametes that are distinct in form, typically characterized as male and female gametes. This means that one type of gamete is usually larger (female) and the other is smaller (male).

2. **Identifying Isogametes**:
- Isogametes are gametes that are morphologically similar, meaning they cannot be distinguished as male or female.

3. **Analyzing the Options**:
- **Funeria**: This organism has isogametes, so it does not have heterogametes.
- **Terris**: Similar to Funeria, Terris also has isogametes, ruling it out as well.
- **Liverworts**: These also produce isogametes, thus they do not have heterogametes.
- **Kara (Chara)**: This organism is known to produce heterogametes, with distinct male and female gametes.
- **Fucus**: Like Kara, Fucus also produces heterogametes, with identifiable male and female gametes.

4. **Conclusion**:
- The algae that have heterogametes are **Kara and Fucus**. Therefore, the correct answer is option C.

### Final Answer:
**Kara and Fucus are the algae having heterogametes.**
