1. Plants Vascular System & Leaves Chapter 21.2 & 21.4

2. Vascular System
Xylem transports water and dissolved minerals from the roots to the rest of the plant.
Moves by capillary action by the physical properties of adhesion and cohesion.
Phloem moves the products of photosynthesis from the leaves to the roots and stems
Moves from the sugars source to the sugars sink, this region shifts seasonally

Site of photosynthesis, creates oxygen
Food supply for herbivores, omnivores, and detrivores
Medicinal properties
Differences within structure used to identify various species
