Sucrose is the most commonly found sugar in phloem sap of flowering plants. It is the main transport sugar molecule in the phloem and is responsible for supplying energy to plant tissues. Glucose is another sugar found in plants but it is mainly stored as starch and not transported in the phloem. Xylose, ribulose, and ribose are sugars found in other biological processes but are less commonly found in phloem sap.
