Answer: Seedless vascular plants can grow taller because they have tissues that support the plant and carry water and nutrients.
Explanation:
Seedless plants are those which lack seed production they have vascular system comprising of xylem and phloem tissues. These tissues help in conduction of water and nutrients from the soil this helps in growth of plants to larger sizes are compared to nonvascular plants that obtain water and minerals via diffusion with the moist soil so their growth is restricted as they do not have well developed vascular system. The example of seedless vascular plants are the ferns. The example of nonvascular plants are mosses.
