To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.
The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.
