Transport (in the phloem)

Transport (in the phloem). Land colonization. Prompted greater shoot growth to reach and compete for sunlight Prompted development of a deeper root system SEPARATES PHOTOSYNTHESIZING REGIONS FROM AREAS WHERE SUGARS ARE USED REQUIRES A DRIVING FORCE FOR THIS LONG-DISTANCE TRANSPORT.
