Ferns break the force of the rain passing through the forest canopy so more water can get absorbed by the soil, and go into the aquifer, and erosion is reduced.

Photosynthetic tissues can distribute sugars through living phloem cells throughout the plant. SVPs are sporophyte dominant with reduced, thalloid gametophytes. Sporophytes are branched with many sites for spore production. They can be divided into two lineages: Lycopodiopsida and Polypodiopsida.

Spores germinate into the gametophyte, which reproduces in wet conditions.

Sporophytes produce megaphylls in the form of fronds that emerge in a curled form (fiddlehead). Spores are produced in clusters called sori.

It emphasizes plant selection based on hardiness zones and specific needs, including the care of geophytes and pond plants.

They have a sporic life cycle with sporophyte predominance whereas their gametophytes are often reduced to prothallium, small hornwort-like plant. Another frequent variant is the underground, mycoparasitic gametophyte. Pteridophyta (with one exception) have true roots. Most of them have vascular tissues and are homoiohydric. This is why seed plants together with ferns have a name vascular plants.
