The phospholipid bilayer is a non covalent aggregate; the lipids and the proteins molecules are held together chemical interactions such as vander waal's forces and hydrogen bond. The vander waals forces hold the hydrophobic tails together while the hydrogen bond helps to stabilize the lipid bi-layer structure.
Osmosis is said to be the tendency of a fluid, usually water, to pass through a semi permeable membrane (as of a living cell) into a solution where the solvent concentration is higher thus equalizing the concentrations of materials on either side of the membrane.
When sugar is placed on a straw berry, the thin film of moisture on the berry skin begins to dissolve the sugar. Once this happens, the dissolved sugar forms a higher solute concentration on the skin of the berry than that found in the (plant) cells of the berry. A concentration gradient is formed and water molecules from the berry cells move down that gradient to the outside of the berry skin and dissolve the sugar to form a gooey solution.
