Bryophyta like to grow in moist places because:

Options

A. Of absence of roots, they has to absorb the moisture from water ground
B. Male gametes require water for swimming
C. They do not have waterproof coating of cutin on their aerial surface to prevent the loss of water
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophyta**: Bryophyta, commonly known as mosses and liverworts, are non-vascular plants that thrive in moist environments. They are often found in shaded areas where moisture is abundant.

2. **Absence of True Roots**: Bryophytes do not possess true roots, stems, or leaves. Instead, they have root-like structures called rhizoids that help anchor them to the substrate but are not effective in water absorption. This means they must absorb moisture directly from their surroundings.

3. **Need for Water in Reproduction**: For sexual reproduction, Bryophytes require water. Male gametes (sperm) need to swim through water to reach the female gametes (eggs) for fertilization. This dependence on water for reproduction is a key reason they grow in moist habitats.

4. **Lack of Waterproof Coating**: Bryophytes lack a waterproof cuticle, which is a protective layer found in many other plants that helps prevent water loss. Without this protective layer, they are more susceptible to desiccation (drying out), making it essential for them to inhabit moist environments to maintain hydration.

5. **Conclusion**: Given these factors—absence of true roots leading to reliance on moisture, the necessity of water for the movement of male gametes, and the lack of a waterproof coating—it is clear that Bryophyta thrive in moist places. Therefore, the correct answer to the question is "all of the above."

**Final Answer**: Bryophyta like to grow in moist places because of the absence of true roots, the requirement of water for male gametes to swim, and the lack of a waterproof coating. Thus, the answer is "all of the above."
