The colorless rootlike projections of mosses, liverworts, and hornworts, which anchor them to the substrate, are called rhizoids. Rhizoids are thread-like structures that emerge from the lower part of the plant’s thallus (body) and extend into the substrate. While they resemble roots, they lack vascular tissue and have a different structure and function.

Rhizoids play an important role in the anchorage of these non-vascular plants. Since mosses, liverworts, and hornworts lack true roots, rhizoids help them adhere to the substrate, which can be soil, rocks, bark, or any other surface where they grow. Rhizoids also aid in the absorption of water and nutrients from the environment.

Unlike true roots, rhizoids are not involved in the transport of substances. Instead, they act more like a sponge, absorbing water and nutrients directly from the surroundings. The absence of vascular tissue in these plants means that water and nutrients are moved through the plant body via diffusion and capillary action.

It is worth noting that not all non-vascular plants possess rhizoids. For example, some liverworts have tiny hair-like structures called scales that help them attach to the substrate. However, rhizoids are the most common and well-known anchoring structures in these types of plants.

In summary, rhizoids are colorless rootlike structures that anchor mosses, liverworts, and hornworts to the substrate. They are involved in absorption of water and nutrients and provide support and stability to these non-vascular plants.
