How are phloem adapted to transport sugar
WebPresumably due to its physicochemical properties, sucrose represents the major transport form of photosynthetically assimilated carbohydrates in plants. Sucrose synthesized in green leaves is transported via the phloem, the long distance distribution network for assimilates in order to supply nonpho … WebPhloem sap is an aqueous solution that contains up to 30 percent sugar, minerals, amino acids, and plant growth regulators. The high percentage of sugar decreases Ψs, which decreases the total water potential and causes water to move by osmosis from the adjacent xylem into the phloem tubes, thereby increasing pressure.
