Osmosis is the net movement of water molecules across a semipermeable membrane from a region of low solute potential to an area of high solute potential (or equivalently, from a region of high solvent potential to a region of low solvent potential). The partially permeable membrane must be permeable to the solvent, but not to the solute, resulting in a pressure gradient across the membrane. Osmosis is a natural phenomenon. However, it can be artificially opposed by increasing the pressure in the section of high solute concentration with respect to that in the low solute concentration. The force per unit area required to prevent the passage of solvent through a selectively-permeable membrane and into a solution of greater concentration is equivalent to the turgor pressure. Osmotic pressure is a colligative property, meaning that the property depends on the concentration of the solute but not on its identity.

Osmosis is an important topic in biology because it provides the primary means by which water is transported into and out of cells.

"Surely she means Osmosis?" I thought to myself, which is described enough times here, and fully expected Google to come back with that when I put the word Hosmosis in just for a giggle.
Google, oddly enough, thought I meant Aolmusic, which is bizarre enough in itself.
But there were also some results for Hosmosis (224). It seems to be an italian word for something (probably osmosis), a name of a character in a book, and a few other random entries. Most of the english entries look to be mis-spellings of osmosis.

Osmosis
The term osmosis describes the movement of a solvent through a semipermeable membrane from a less concentrated solution to a more concentrated one. Water is sometimes called "the perfect solvent," and living tissue (for example, a human being's cell walls) is the best example of a semipermeable membrane. Osmosis has a number of life-preserving functions: it assists plants in receiving water, it helps in the preservation of fruit and meat, and is even used in kidney dialysis. In addition, osmosis can be reversed to remove salt and other impurities from water.

I think you mean OSMOSIS - the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.

From Wikipedia:
Osmosis is the net movement of water molecules across a semipermeable membrane from a region of low solute potential to an area of high solute potential (or equivalently, from a region of high solvent potential to a region of low solvent potential). The partially permeable membrane must be permeable to the solvent, but not to the solute, resulting in a pressure gradient across the membrane.
