Prize share: 1/3
Our bodies are made up of cells that contain organelles, components with various functions. Albert Claude's research with the newly developed electron microscope and his methods for separating the various parts of pulverized cells using a centrifuge opened up new opportunities for studying cells in detail. In 1955 Christian de Duve discovered previously unknown organelles in the cell, lysosomes. These have important functions in decomposing different types of materials, such as bacteria and parts of cells that have worn out.
