The product of fertilization in Funaria/Selaginella/Fern is called

Options

A. Zygote
B. Zygospore
C. Oospore
D. Oosphere.

Answer

To solve the question regarding the product of fertilization in Funaria, Selaginella, and Fern, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Funaria is a type of moss and belongs to the division Bryophyta.
- Selaginella is a type of club moss and belongs to the division Pteridophyta.
- Ferns are also part of the division Pteridophyta.

2. **Understand the Reproductive Structures**:
- In both Funaria and Selaginella, sexual reproduction occurs through specialized structures.
- The male reproductive structure is called an **antheridium**, which produces male gametes (antherozoids).
- The female reproductive structure is called an **archegonium**, which produces the egg.

3. **Fertilization Process**:
- During fertilization, the male gamete (antherozoid) fuses with the female gamete (egg).
- This fusion results in the formation of a new structure.

4. **Identify the Product of Fertilization**:
- The structure formed after the fusion of the male and female gametes is a diploid structure known as a **zygote**.
- This zygote will eventually develop into a new organism.

5. **Eliminate Other Options**:
- **Zygospore**: This term is not applicable here as it refers to a different type of reproductive structure found in certain algae.
- **Oospore**: This structure is typically associated with certain fungi and algae, not with Funaria or Selaginella.
- **Oosphere**: This is a term related to the egg cell but is not the product of fertilization.

6. **Conclusion**:
- The correct answer to the question is **Zygote**.

### Final Answer:
The product of fertilization in Funaria, Selaginella, and Fern is called a **Zygote**.
