Create a fully labeled chloroplast diagram on a white background. Draw a lens-shaped organelle in cross section with a smooth green outer line labeled "Outer membrane", a second line just inside it labeled "Inner membrane", and a narrow gap between them labeled "Intermembrane space". Shade the enclosed interior pale green and label it "Stroma". Suspended freely in that stroma, attached to neither membrane and never drawn as folds of the inner membrane, draw five separate piles of flattened discs: label one pile "Granum", one disc "Thylakoid", the space inside a disc "Thylakoid lumen", and the flat membranes bridging the piles "Stroma lamellae". Add a loop labeled "Chloroplast DNA", dots labeled "Ribosomes", and two pale ovals labeled "Starch grain".
