Sugar transports does not require energy.
only phloem cells with nuclei can perform sugar movement.
Diffusion can account for the observed rates of transport.
Movement can occur both upward and downward in the plant.

phloem transports food. think ffffffloem transports fffffood, and it always moves from source to sink. so if u make the food thru  the leaves during photosynthesis, its going to go wherever it needs to in order to feed the plant. SO, movement can occur upwards and downwards!
