2.54 Transpiration

Notes


Word equation:
Liquid ---------- Heat (Sunlight) ---->  Gas

Process:
1. Water (osmosis): Root system -> Stem -> Leaf -> Stomatal pores to evaporate
2. Sunlight hits leaf surface;
       - Leftover from photosynthesis absorbed by other cell structures -> Produces Heat
       - Water from xylem: Spongy mesophyll -> Cavity 'above' stomata
          - Where phase change occurs
3. Vapor inside (100% humidity) --- Diffusion ----> Outside environment (h < 100%)
