Xylem vs Phloem Transport
Plants have two separate transport systems to move water, minerals, and food throughout their structure.
Which tissue carries sugar, and does it move up or down?
What is Xylem vs Phloem Transport?
"Transpiration (xylem) and translocation (phloem) are the two main transport processes in plants."
What is transpiration?
Which set of conditions would usually increase the rate of transpiration?
Why does high humidity reduce transpiration?
Plant Transport
Xylem: Moves water and minerals from roots to leaves (one way).
Phloem: Moves dissolved sugars (translocation) to where they are needed (two ways).
Xylem vessels are dead; phloem cells are living.
Phloem transport is "bidirectional" - it can move nutrients to roots for storage OR to buds for growth.
