Cells
A drop of oil in
water can demonstrate the power of surface tension in forming a cell wall between two
dissimilar
materials like oil (a non-polar carbon compound) and water (a polar molecule).
Non-polar molecules and
atoms along a
boundary tend to be only partially bonded so they
attract charged polar molecules. Soon, polar carbon
compounds would
congregate along the
perimeter of the cell wall, fortifying it.
