No, non-vascular plants do not have roots.
Explanation:
Non-vascular plants, such as mosses, liverworts, and hornworts, lack a vascular system (xylem and phloem) for transporting water and nutrients. This limits their size and structural complexity. Instead of true roots, which are characteristic of vascular plants, they possess structures called rhizoids.
Rhizoids vs. Roots:
| Feature | Rhizoids | Roots |
|---|---|---|
| Structure | Simple, hair-like filaments | Complex, multi-cellular organs |
| Function | Anchorage and some water absorption | Anchorage, water and nutrient absorption, storage |
| Vascular Tissue | Absent | Present |
| Complexity | Less complex | More complex |
Rhizoids are primarily used for anchorage, securing the plant to a substrate. While they can absorb some water and nutrients, their role in this regard is limited compared to the extensive absorptive capabilities of true roots. Roots, found in vascular plants, are much more complex, containing vascular tissue that efficiently transports water and nutrients throughout the plant. They also play a crucial role in anchoring the plant and can serve as storage organs.
Conclusion:
Non-vascular plants rely on rhizoids for anchorage, rather than true roots for water and nutrient uptake. This is a key distinction between non-vascular and vascular plants.
