Text solutionVerified

Food is transported by vascular tissue phloem from a source to sink. Source is a part that synthesises food and sink is a part that stores or needs the food. Since source and sink can be reversed depending on plant’s need, therefore direction of movement of sugar in phloem can be bidirectional, i.e., both upwards or downwards.
Phloem sap is generally alkaline with pH ranging from 7.3 - 8.5.
