Question

What are common characteristics to both to bryophytes and to seedless vascular plants?

Answer 1

Reliance on water, simple bodies

Explanation:

Both bryophtes (the mosses) and seedless vascular plants (mostly ferns) rely on water fertilization, do not have complex xylem and phloem, do not have complex gametophytes, and simple root like systems instead of the roots you see in other vascular groups. Some groups of seedless vascular plants, like bryophtes are homosporus. Neither groups produce fruits or flowers. Both also have archegonia and antheridia.
