Explanation:
Detailed explanation-1: -What are rhizoids? Rhizoids are root-like structures that grow at the base of many bryophytes, or mosses, hornworts and liverworts. Rhizoids help anchor the plant to the substrate.
Detailed explanation-2: -Rhizoids played essential roles in the early evolution of land plants. All liverworts, the closest living relatives of the first land plants, produce unicellular rhizoids, except for Haplomitrium.
Detailed explanation-3: -Rhizoids in the mosses are multicellular, but uniseriate (exception: Andreaeidae mosses have biseriate rhizoids). This means that more than one cell is needed to make a rhizoid and that these cells are aligned end to end, forming a filament.
