Five different types of taste receptors have been identified in humans.  These are salty, sour, sweet, bitter and umami.  Taste receptors consist of specific types of proteins incorporated into the plasma membrane of taste receptor cells, which are clustered together in structures called taste buds.  All five receptor types are present in each taste bud, which are distributed over most of the tongue surface area.  Olfactory receptors are located in the nasal cavity and consist of several thousand different types, each type specific for a different odorant molecule (ligand).   You may need to research this on the internet.  Be sure to site your sources. If you plug your nose, red wine and coffee taste exactly the same.

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.
