Explain how ferns are better adapted to terrestrial life than mosses
- Ferns are better adapted to terrestrial life than mosses because;
- Ferns have rhizomes (horizontal underground stems) which act as organs of perennation, allowing the ferns to survive unfavorable climatic conditions unlike mosses.
- Sporophytes of ferns have true roots for anchorage and transport of water and mineral salts, unlike mosses which have false roots (rhizoids)
- Ferns produce, more spore than mosses. These increases their chances of reproduction and colonization of habitat compared to mosses.
- Ferns have a well-developed vascular system that supplies the whole plants with water and food.
- The lignified xylem offers more support to the fern.
- Ferns have broader leaves which present a larger surface area for photosynthesis.
- Sporophyte generation of ferns is nutritionally independent while that of the mosses depends on the gametophyte for nutrients.
- Ferns have true stems to support the leaves to obtain enough light for photosynthesis. They also help them to withstand air currents present in the terrestrial environment.
- Leaves of ferns have waxy cuticle to prevent desiccation.
