    surface area of a beetroot (Beta Vulgaris) piece? Background The membrane consists of a phospholipid bilayer which is semi permeable. Osmosis is the passive movement of water molecules from an area of high water potential to an area of low water potential across a semi-permeable membrane. It is easy for water molecules to pass through this membrane however solutes that are big in size may find it hard to as the semi-permeable membrane is selective to the smaller particles. This may cause a change in
