Detailed explanation-1: -They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).
Detailed explanation-2: -They include pteridophytes, gymnosperms and angiosperms. Non-vascular plants lack a specialised vascular system for transporting water and nutrients. They may contain simple structures that may specialise to perform transportation, e.g. algae and bryophytes.
Detailed explanation-3: -Nonvascular plants lack differentiated tissues like vascular tissues, which separate them from vascular plants that have vascular tissues to transport nutrients and water. They also lack stems, roots, and leaves. But they have stem-like, root-like, and leaf-like structures that work just like stem, roots, and leaves.
Detailed explanation-4: -Non-vascular plants are short in height as they do not have a vascular system that is xylem and phloem. Except for bryophytes, pteridophytes, gymnosperms, and angiosperms are all vascular plants which possess the vascular system of xylem and phloem.
