Grana (stack of thylakoids) Stroma (solution)

Why are leaves GREEN? Sunlight = White light and contains all colors of the spectrum Leaves contain pigments chlorophyll a & b and carotenoids Chlorophylls absorb all colors besides green = reflect green

Why do leaves change in the fall? Leaves loose their chlorophyll as they die Carotenoids (pigment) reflect yellows, oranges, greens
