The process of loading and transport of food through the phloem tissue involves which of the following factors?

Question

Quizplus · Accepted Answer

All of these factors are involved in phloem transport. Osmosis, active transport, and differences in water potential are all necessary for the movement of sugars and other organic molecules through the phloem. Mass flow is also involved, as the movement of fluids within the phloem is driven by pressure differences between source and sink tissues.
