Caption: Coloured Transmission Electron Micrograph of a section through the unicellular green algae, Chlamydomonas asymmetrica. The micrograph shows the arrangement of chloroplasts (green) around the circumference of the cell. Chloroplasts are the sites of photosynthesis in higher plants & green algae. They contain light-sensitive chlorophyll pigments, which react to produce sugar from carbon dioxide. Sugar can be stored in the chloroplast as starch (yellow). Algal chloroplasts often contain a body called a pyrenoid, seen as the blue mass at the centre of the large area of starch. Magnific- ation: x3100 at 35mm size, x6000 at 6x6cm size. Reference: MICROCOSMOS, figure 1.8, page 10.
