Rhizoids are fine, hair-like structures that serve the function of anchoring non-vascular plants to surfaces. However, depending on the specific type of non-vascular plant, there are various synonyms for rhizoids. For instance, mosses have protonema, which are thread-like structures that grow into rhizoids. Liverworts, on the other hand, have thalli, which are flat bodies that produce scales and rhizoids. Similarly, hornworts develop characteristic symbiotic fungi that give rise to rhizoids called arbuscules, which are essential for nutrient absorption. Overall, the variety of synonyms for rhizoids is fascinating and a testament to the diversity and adaptability of non-vascular plants.
