2.20 Leaf adaptation for photosynthesis

1. Large surface area - to collect light
2. Thin - Fast diffusion
3. Palisade cells - Contain Chloroplast - near top of leaf so photosynthesis can take place faster
4.Many Chloroplast-Chlorophyll--> Light collecting pigment
5. CO2-Stomatal Pore
6. Mesophyll - Many spaces 
-which allows diffusion of CO2 
-and movement of H2O
7. Vascular Bundle (vein that comes into the leaf)
-H2O to leaf
-Sap (dissolved sugars) out of leaf
