False colour transmisson electron micrograph of a chloroplast in the leaf of a pea plant Pisum sativum. The chloroplast is the site of photosynthesis; the process by which plants obtain carbohydrates from carbon dioxide using the energy from sunlight. The contents of the chloroplast are bound together by a double membrane. Internally, the chloroplasts consists of stacks of flattened membranes called grana (black threadlike) suspended in a matrix of hydrophilic proteins. The grana contain the chlorophyll pigments & are the sites of light reactions during photosynthesis. The large white oval is a starch body, one of the products of photosynthesis. Magnification X70,000 (at 10x inch size).
