What helps ferns club mosses and horsetails grow taller than mosses?

Ferns, club mosses, and horsetails have vascular tissues that allow them to transport water and nutrients more efficiently than mosses, which lack these structures. This vascular system supports greater height and structural complexity, enabling them to grow taller. Additionally, their ability to produce spores instead of relying solely on water for reproduction allows them to thrive in a wider range of environments. These adaptations give them a competitive advantage over non-vascular mosses.
