Detailed explanation-1: -Mosses are flowerless plants that grow in clumps. They don’t have roots. Instead they have thin root-like growths called rhizoids that help anchor them. Because they don’t have roots and stems to transport water, mosses dry out very quickly, so they are usually found in moist habitats.

Detailed explanation-2: -What is the difference between the rhizoids of liverworts and mosses? Mosses have threadlike rhizoids that help them in anchoring to their substrate whereas liverworts have a single celled rhizoid.

Detailed explanation-3: -Rhizoids are multicellular in the mosses. All other land plants develop unicellular rhizoids and root hairs.

Detailed explanation-4: -In land plants, rhizoids are trichomes that anchor the plant to the ground. In the liverworts, they are absent or unicellular, but multicelled in mosses. In vascular plants they are often called root hairs, and may be unicellular or multicellular.

Detailed explanation-5: -rhizoid, a short, thin filament found in fungi and in certain plants and sponges that anchors the growing (vegetative) body of the organism to a substratum and that is capable of absorbing nutrients. In fungi, the rhizoid is found in the thallus and resembles a root.
