DENDROLOGY

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

Detailed explanation-4: -In plants, such as liverworts and mosses (division Bryophyta), rhizoids attach the gametophyte to the substratum and facilitate the absorption of minerals and water.
