Which feature helps pteridophytes survive better than bryophytes in places with limited moisture?
Presence of vascular tissues for transport of water and nutrients
Bryophytes (mosses, liverworts) lack vascular tissue, so water and minerals move only by slow cell-to-cell diffusion; this restricts them to damp, shady places.
Pteridophytes (ferns, horsetails) are the first land plants with true vascular tissues — xylem to conduct water and minerals and phloem to conduct food — along with true roots, stems and leaves.
Xylem lets them draw water from deeper soil through roots and carry it throughout the body, so they can survive where moisture is more limited.
Absorbing water through the whole body surface is a bryophyte feature, not an advantage. Absence of true roots, stems and leaves describes bryophytes, not pteridophytes. Dependence on water for male gamete movement is a limitation shared by both groups.
Hence, the answer is Presence of vascular tissues for transport of water and nutrients.
