Which type of sexual reproduction is found in fucus?

Answer

### Step-by-Step Solution

1. **Understanding Fucus**: Fucus is a genus of brown algae commonly found in marine environments. It is important to know the type of reproduction it employs.

2. **Identifying the Type of Reproduction**: Fucus exhibits a type of sexual reproduction known as heterogamy. This means that it produces different types of gametes.

3. **Types of Gametes in Fucus**:
- **Isogamy**: In this type, the male and female gametes are morphologically identical. They look the same in structure and shape.
- **Anisogamy**: In anisogamy, the gametes differ in morphology. The male and female gametes have different structures, making them distinguishable from one another.
- **Oogamy**: This is a specific form of anisogamy where the female gamete is significantly larger than the male gamete. The male gamete is usually motile (sperm), while the female gamete (egg) is non-motile.

4. **Conclusion**: Fucus shows a heterogamous mode of reproduction, which includes isogamy, anisogamy, and oogamy.

### Final Answer
Fucus exhibits heterogamous sexual reproduction, which includes isogamy, anisogamy, and oogamy.
