False colour transmisson electron micrograph of a chloroplast in the leaf of a pea plant Pisum sativum. The chloroplast is the site of photosyn- thesis; a process by which plants obtain carbohyd- rates from carbon dioxide,using the energy from sunlight.The contents of the chloroplast are bound together by a double membrane.Internally,chlorop- lasts consists of stacks of flattened membranes called grana (black thread-like) 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,a photosynthesis product.
