Cells are small. To see them you need a microscope, and to see theircontents in detail you need an electron microscope. Objects so minute that
they cannot be seen with the naked eye are - by definition - remote from everyday experience. This makes it hard to grasp the scale of cells and their contents. And without a grasp of scale it is impossible to acquire a clear mental picture of a cell.
