Do ferns and mosses have vascular tissue?
The vascular tissues in the more advanced ferns and “fern allies” are made up of xylem and phloem, which conduct water, nutrients, and food throughout the plant body. Mosses and liverworts are lumped together as bryophytes, plants lacking true vascular tissues, and sharing a number of other primitive traits.
Do Ferns have phloem?
The stiff cell walls of the xylem also provide support for the fern plant as it grows taller. The other vascular tissue, phloem, is responsible for moving glucose throughout the plant. Ferns also contain true roots, stems and leaves.
