Question

what trait do nonvascular plants and seedless vascular plants have in common?
they both reproduce using spores.
they both lack designated transport systems.
they both have segmented leaves.
they both produce fruits.

Explanation:

Nonvascular plants (like mosses) reproduce via spores. Seedless vascular plants (such as ferns) also reproduce using spores. Nonvascular plants lack vascular transport systems, but seedless vascular plants have them. Neither necessarily have segmented leaves. Fruits are produced by angiosperms (flowering plants), which neither nonvascular nor seedless vascular plants are.

Answer:

They both reproduce using spores.
