In bryophytes fertilization takes place :-

Options

A. At low temp
B. In dry condition
C. In presence of water
D. In above all situation

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophytes**: Bryophytes are non-vascular plants, often referred to as amphibians of the plant kingdom because they require water for reproduction.

2. **Role of Water in Fertilization**: In bryophytes, fertilization involves the movement of male gametes (sperms) to female gametes (eggs). This process is heavily dependent on water.

3. **Mechanism of Fertilization**:
- **Dehiscence of Antheridia**: Water is necessary for the antheridia (male reproductive structures) to release sperm.
- **Swimming of Sperm**: The sperm cells are motile and swim through water to reach the archegonia (female reproductive structures).
- **Attraction to Egg**: The sperm are attracted to the egg in the archegonia by a chemical stimulus, which is often in the form of sugars.

4. **Conclusion**: Therefore, for fertilization to occur in bryophytes, the presence of water is essential. This allows the sperm to swim to the egg and successfully fertilize it.

**Final Answer**: In bryophytes, fertilization takes place in the presence of water.
