Alga. Scanning electron micrograph of an unidentified alga from a lake in Vietnam. The term "algae" covers many different organisms capable of producing oxygen through photosynthesis (the process of harvesting light energy from the sun to generate carbohydrates). These organisms are not necessarily closely related. However, certain features unite them, while distinguishing them from the other major group of photosynthetic organisms: the land plants. Magnification: x 4000 when printed at 10cm wide. Specimen collected from Vietnam courtesy of Mike Allen, Plymouth Marine Laboratory.
