    Polar - non symmetrical with polar bonds
    Non-polar - has polar bonds but symmetrical or no polar bonds

    Adding to above, polar molecules have a partially positive side, and a partially negative side.

    If a molecule is polar, it means that one atom/atoms attract electrons more strongly than the other atoms in the molecule.

    Slightly misleading. Non polar molecules can still contain polar bonds if they are symmetrical

    Also, If a molecule is polar, it will dissolve in a polar solvent (i.e Water). If it is nonpolar, it will dissolve in a non-polar solvent such as hexane.

    *Due to differences in electronegativity between atoms. Resulting in the more electronegative atom more strongly attracting the electron density toward itself in a covalent bond. Resulting in a dipole.

    Polar molecule = regions of positive and negative charges (so must be assymetrical) and has polar bonds
    Non-polar = no regions of positive and negative charges + polar bonds OR no polar bonds

    Can some one relate polar and non polar through active/passive transport through a phospholipid bilayer?

    If an atom is more electronegative than another atom, it will have a greater attraction for the bonding pair of electrons than other atom< so the bonding electrons will be closer to it. This crates a small charge difference which is a permanent dipole. Since the electrons are not evenly distributed , the bond is now polar.
