Rhizoids are simple, hair-like projections that grow out of the epidermal cells of bryophytes.
Bryophytes are an informal division that consists of 3 groups of non-vascular plants, namely mosses, liverworts, and hornworts. Prominent bryophytes characteristics are the absence of true roots stems and leaves.
Function of Rhizoids:
Rhizoids perform the function of roots, essentially anchoring the plants into the surface.
Though, rhizoids do not absorb nutrients like traditional plant roots.
