In spring, stored carbohydrate in a root is converted to sucrose. New shoots are growing above the ground but have not yet developed green leaves.
How is this sucrose transported to the new shoots?
upwards through phloem by translocation
upwards through xylem by transpiration
downwards through phloem by translocation
downwards through xylem by transpiration
