organelles that convert light energy to chemical energy
the molecule capable of accepting electrons and becoming reduced; the electrons will be transferred to the electron transport chain
the dense fluid that is surrounded by two membranes within a chloroplast
a system composed of a reaction-center complex surrounded by several light-harvesting complexes
Down
a complex that consists of various pigment molecules (such as chlorophyll a/chlorophyll b) that are bound to proteins
the green pigment which gives leaves their color and resides within thylakoid membranes of the chloroplast
The photosystem that functions first within the light reactions; contains P680; converts water to oxygen; passes electrons to the other photosystem
space segregated from the stroma via thylakoid membranes
sacs that make up a third membrane system in chloroplasts that contain pigment
