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: -Unlike most other plants, mosses don’t have roots. Instead they have rhizoids, which are small hairlike structures. Their main function is anchoring the plant to rock, bark or soil.

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

Detailed explanation-4: -Rhizoids are protrusions that emerge from the bottom epidermal cells of bryophytes. Rhizoids can be single-celled or multicelled root-like structures. Non-vascular plants such as bryophytes have thallus-like plant bodies that are prostrate or upright.

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.
