Mosses and ferns are found in moist and shady place because both

Options

A. Requires water for growth
B. Requires water for fertilisation
C. Male gametes are flagellated
D. Both (a) and (b)

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: Mosses and ferns are both types of plants. Specifically, mosses belong to the group Bryophyta, while ferns belong to the group Pteridophyta.

2. **Habitat Preference**: Both mosses and ferns are typically found in moist and shady environments. This is a crucial aspect of their ecology.

3. **Reproductive Requirements**: The reproduction of both mosses and ferns involves water. In ferns, male gametes (sperm) are flagellated and require a film of water to swim to the female gametes (eggs) for fertilization.

4. **Fertilization Process**: The need for water during fertilization is essential for these plants. Without sufficient moisture, the sperm cannot reach the egg, preventing fertilization from occurring.

5. **Conclusion**: Therefore, the primary reason mosses and ferns are found in moist and shady places is that they require water for fertilization.

**Final Answer**: Mosses and ferns are found in moist and shady places because they require water for fertilization.
