1. Draw 8 phospholipid molecules arranged to show how the phospholipids will orient themselves on the surface of the water.  This should be a single layer or monolayer. Label the hydrophilic and hydrophobic parts of a phospholipid.   2. Now draw 8 phospholipids, arranged so that they are submerged in the water while still maintaining the correct hydrophobic and hydrophilic interactions. This structure is called a micelle. 3) Draw a structure that is both submerged in water and contains water on the inside. Draw phospholipids oriented to form a cell membrane, with the tails in and the hydrophilic heads out.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
