Micro-organisms

Microscopic life has a huge impact on the world around us and even inside our own bodies. In this topic, you will discover how some unicellular organisms are specially adapted to survive in different environments, using unique structures to move, feed and reproduce. By understanding these tiny organisms, we can see how even the smallest forms of life play an essential role in sustaining life on Earth.
