Green alga, TEM Featured 21 Mar 1985 Print

Green alga, TEM

Transmission electron micrograph of a section through a single cell green algae, Chlamydomonas asymmetrica. The micrograph shows the arrangement of chloroplasts, dark-stained bodies, around the circumference of the cell. Chloroplasts are the sites of photosynthesis in higher plants & green algae. They contain the light sensitive chloroplhyll pigments, which in a complex reaction leads to the production of sugar from carbon dioxide. Sugar may be store in the chloroplast as starch (white). Algal chloroplasts often contain a body called a pyrenoid (dark mass at centre of starch). Its function is unknown. Magnification X18, 000 (10x8 size), X 2570 (at 35mm size)
