False colour transmission electron micrograph of a dividing chloroplast in the leaf of the pea plant, Pisum sativum, showing the central area constricting to partition the cell into two daughter cells. Within the chloroplast are the stacks of grana; flattened, membranous layers enclosing a space (threadlike), which store the photosynthetic pigments, the chlorophylls. A large white starch body, one of the products of photosynthesis, is visible in the right hand cell. The patchy white areas scattered throughout the chloroplast are nucleoids, the sites of chloroplast DNA. Magnification: X40 000 at 10x8 inch,X5700 at 35mm size.
