Answer Key
Functions of the Chloroplast and the Mitochondrion
A. Inner Membrane: Less permeable than outer membrane, studded with proteins
B. Outer Membrane: Permeable to small organic molecules
C. Thylakoids: Fluid filled sac, light dependent reactions, chlorophyll pigment, stacks called grana
D. Stroma: Fluid in the surrounding granum in the chloroplast
E. Chloroplast: Site of Photosynthesis synthesizing light energy, CO2, H2O into glucose and oxygen
