Webb25 jan. 2024 · Translocation in Phloem. The movement of various molecules, like sucrose, amino acids, etc., through phloem in a plant, is called translocation in the phloem. The translocation in the phloem is not affected due to gravity. Sucrose is instead translocated from the point of supply (leaf) to the point of metabolism or storage, referred to as a sink.
WebbTranslocation is the movement of sucrose around a plant from a source to a sink. It’s bidirectional, which means it can transport substances both up and down the plant.
