Syngamy can occur outside the body of the organism in

Options

A. A. mosses
B. B. algae
C. C. ferns
D. D. fungi

Answer

**Step-by-Step Solution:**

1. **Understanding Syngamy**: Syngamy is the process of fertilization where male and female gametes fuse to form a zygote. This can occur either inside or outside the organism's body.

2. **Analyzing the Options**:
- **A. Mosses**: In mosses, syngamy occurs inside the female gametophyte. The gametes are produced within the plant structure, leading to the formation of a zygote that is protected.
- **B. Algae**: In algae, the gametes are released into the water where they can fuse freely. This process occurs outside the organism's body, making it a suitable candidate for syngamy occurring externally.
- **C. Ferns**: Similar to mosses, ferns have gametes that fuse inside the gametophyte, which is part of the plant structure.
- **D. Fungi**: In fungi, while there is a process of sexual reproduction, the fusion of gametes typically occurs within the structures of the fungus.

3. **Conclusion**: Based on the analysis, the only option where syngamy occurs outside the body of the organism is **B. Algae**.

**Final Answer**: B. Algae
