- Xylem transports: Water and mineral salts from roots to leaves
- Phloem transports: Sugars and amino acids from leaves to all plant parts
- Direction: Xylem flow is one-way (up), phloem flow is two-way
- Cell status: Xylem cells are dead, phloem cells are living
- Driving forces: Xylem uses transpiration pull, phloem uses pressure flow
- Root adaptations: Root hairs increase surface area by up to 1000x

Quick recall flashcards
What is phloem tissue?
A plant tissue that transports sugars and amino acids from the leaves to other parts of the plant.
