The eukaryotic cell is the basic unit of animals and plants. Through the microscope, it looks highly structured and subdivided in many membrane-bound compartments. Each compartment has a specific function, and its membrane is populated by specific molecules. How does the cell preserve this amazing internal order, and (in the absence of pathologies) not degrade into a shapeless bunch of molecules? Such degradation is countered by a continuous process of molecular sorting by which similar molecules are collected and dispatched to the 'right' destinations, similarly to what happens when a house is kept clean and tidy by daily chores. It's still mysterious, however, how a living cell may achieve this task without a supervisor directing it.
