(Biology) Polarity is also an essential and common feature in organisms, particularly at the cell level. When a chemical species is said to be "polar," this means that the positive and negative electrical charges are unevenly distributed. Water is a polar molecule and also acts as a polar solvent. hydrophilic: having an affinity for water; able to absorb, or be wetted by water; hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water; polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.
