nonvascular tissue
A plant that lacks the tissues to conduct water and other materials.
A thin, root-like structure found in fungi and mosses.
seedless vascular plant
A plant that has tissues that conduct water and other materials but does not reproduce by forming seeds, such as ferns, club mosses, and horsetails.
seed plant
A vascular plant that produces seeds through sexual reproduction, such as angiosperms and gymnosperms.
