Bryophytes do not possess true roots, stems, or leaves.1

While these plants may exhibit structures that resemble stems, roots, and leaves, these are found on the gametophyte generation rather than the sporophyte. In contrast, true roots, stems, and leaves are characteristic of the sporophyte generation in vascular plants.2

Instead of true roots, bryophytes are typically attached to their substratum by threadlike structures called rhizoids, which also assist in the absorption of water and minerals. Because bryophytes lack specialized vascular tissue for internal conduction, they are classified as nonvascular plants.231
