👉 Radiotropism is a property of certain proteins in cells, which can cause them to move towards or away from each other. This movement is called "radiation" because it's caused by the movement of electrons through a protein structure and can be seen as an electric field. For example, in the cell membrane, a protein called the voltage-gated ion channel (VGO) regulates the flow of ions across the cell membrane. When a neuron sends a signal to the VGO, the
