If water molecules inside and outside of a cell became non polar , how would the transport of materials in and out of the cell be affected

The water will move in and out freely. The material transport which is due to the water transport will be affected.

Explanation:Water is a partially polar molecules. Many ionic compounds and ions travel inside and outside the cell due to attachment with water molecule.As well as water movement is controlled due to its polar nature through cell membrane. and the cytoplasm and outer environment is separate due to non polar cell membrane.If the water become non polar then the movement through cell membrane will be easy for water. And the molecules dissolved in water will also be transported uncontrollably.
