Spirogyra algae. Light micrograph of filaments from a Spirogyra sp. alga,showing its spiralling bands of chloroplasts (green). Central nuclei (round) are also seen in each cell. Chloroplasts are the site of photosynthesis,the process of obtaining energy from sunlight. Spirogyra is a common freshwater alga. In favourable conditions it can grow rapidly,forming blooms that deprive other aquatic life of nutrients. Magnification: x13 when printed at 10 centimetres wide | |
