Polarity is an essential and common feature in organisms, particularly at the cell level. Example: polarity of cells in a developing embryo (during embryogenesis) polarity of cells in axis formation.
Molecular shape is the arrangement of the atoms that is three-dimensional and that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism and biological activity.
:) Sry if this is confusing.
