Palisade Cell

Chloroplast Cross Section

Plastid Pigment types

Light Dependent Rundown - Water is heated using photons of light -Hydrogen ions are separated from water - H ions travel down the electron transport chain -ADP + H= ATP -NADP+H=NADPH -ATP and NADPH drive the Calvin Cycle -Oxygen is byproduct Photosystem I- ATP is created Photosystem II- NADPH is created

Dark Reaction of Photosynthesis -3 Carbon Dioxide molecules enter the cycle -ATP and NADPH are used to combine the carbon dioxide molecules together. -Glucose molecules can then be combined into units of 3’s to create different sugar types. Glucose, Fructose, etc
