NONVASCULAR
They are attached to the places where they live by means of their root-like rhizoids.
![Page 7: Plant kingdom](https://reader034.vdocuments.net/reader034/viewer/2022050808/546a6f01af7959973b8b61a5/html5/thumbnails/7.jpg)
NONVASCULAR
They do not have true roots, stems and leaves so they grow very close to damp grounds, stone walls or tree trunks.

LIVERWORTS
Are flat and ribbonlike
![Page 9: Plant kingdom](https://reader034.vdocuments.net/reader034/viewer/2022050808/546a6f01af7959973b8b61a5/html5/thumbnails/9.jpg)
MOSSES
have many small leaflike structures.
![Page 10: Plant kingdom](https://reader034.vdocuments.net/reader034/viewer/2022050808/546a6f01af7959973b8b61a5/html5/thumbnails/10.jpg)
HORNWORTS
grow flat leaves on top of each other
![Page 11: Plant kingdom](https://reader034.vdocuments.net/reader034/viewer/2022050808/546a6f01af7959973b8b61a5/html5/thumbnails/11.jpg)
When nonvascular plants mature, they also form different reproductive structures.
![Page 12: Plant kingdom](https://reader034.vdocuments.net/reader034/viewer/2022050808/546a6f01af7959973b8b61a5/html5/thumbnails/12.jpg)
Liverworts develop “umbrella-like” structures that produce eggs and sperms.
![Page 13: Plant kingdom](https://reader034.vdocuments.net/reader034/viewer/2022050808/546a6f01af7959973b8b61a5/html5/thumbnails/13.jpg)
Eggs and sperms in Hornworts are seen as thin “thorn-like” structures.
