Hands-On Learning

The specimen shows bacterial endospores. Some soil sample was incubated in water with some carbohydrate source (potato tuber). It was smeared on a slide and stained with Basic Fuchsin which cannot penetrate endospore thus making it appear as a clear white speck. The rest of the cell has been coloured red-magenta.
