The world of microscopic, single-celled organisms is no less diverse and complex than the visible realms of life. Bacteria, archaea, protists – each group exhibits a distinct molecular structure, biochemistry, and physiology. Yet, they remain intricately interconnected, engaging in symbiosis and exchanging metabolic products.

Single-celled organisms display an immense variety of shapes and sizes, ranging from a mere 0.3 micrometres in certain bacteria to an astonishing 20 centimetres in deep-sea xenophyophores. The vast majority of these unicellular organisms are completely invisible to the human eye.
