Once plants had evolved this level of controlled water transport, they were truly homoiohydric, able to extract water from their environment through root-like organs rather than relying on a film of surface moisture, enabling them to grow to much greater size.
Unha vez que as plantas evolucionaron ata este nivel no control do transporte de auga, eran xa autenticamente homoiohídricas, e podían extraer auga do seu ambiente a través de órganos similares a raíces en vez de teren que depender dunha película húmida superficial, o que lles permitiu crecer ata tamaños maiores.
