Bryophytes have also been utilized by humans for a number of purposes both historically and in the present day. She walks through the different growth forms and puts them in the larger picture of land plant evolution. Furthermore, rhizoids perform the function of roots, essentially anchoring the plants into the surface. They produce seeds in small cones. Bryophytes can be found in wet environments all around the world. Canary moss is the lichen Parmelia perlata.
