Ins and Outs of Tree Transportation
• Phloem
• Xylems
5
Pressure
• Water evaporates
• Creates low pressure
• Pulls the water up
6
Our Goal
• Distributing clean water to off-grid
communities around the globe using
transpiration

Phloem
• In vascular plants, phloem is the living
tissue that carries organic nutrients, in
particular, sucrose, a sugar, to all parts
of the plant where needed.
