What is Translocation?
Transport of soluble products of photosynthesis using energy is called translocation and it occurs in the phloem.
Give an example when the phloem moves materials according to the plants needs?
In the spring, sugar stored in the root tissue would be transported to the buds which need energy to grow.
What are the uses of the plant transport system?
Plant transport systems will move energy stored in leaves and raw materials from roots.
