osmosis is the transportation of water goin in and other of the cell rite?
when there is a higher contration inside the cell doesnt the water then leaves the cell? so why when you take a shower for a long time you skin wrinkles.
your skin wrinkles because water leaves ur cell but how can that be when you are adding more mosit to the room than b4 shouldnt the water enter you cells inside and make it burst? and why dont our skin wrinkle when we are out in the desert?

well here's what i found (courtesy of Ask.com ;))

Quote: Your skin is made up of two layers. The outer layer is called the epidermis and the lower level is the dermis. The outer layer (epidermis) produces an oily substance called sebum. You can see this substance when you touch a window or mirror and your "oily" fingerprint is left there. One job sebum does is it keeps water out of your skin—a job that it does very well. However, after long periods of time in a swimming pool, shower, or bathtub, much of the sebum is washed off and your outer layer of skin starts to absorb water. As it absorbs water it swells, but since the epidermis is "tied" down to your dermis in certain spots, it expands more where it is not "tied" down and this causes your skin to wrinkle. The difference between your skin and a raisin is that raisins wrinkle because they shrink, but your skin wrinkles because it is getting bigger.

No when there is a higher concentration of something in a cell the water tends to go towards the higher concentration.

If there is higher concentration (of salts) inside the cell, water enters it; water doesn't leave the cell. It is important to distinguish between the terms "higher concentration" and "higher water concentration". They make a world of difference.

Think of a dilute solution as having a high water concentration and a concentrated solution as having a lower water concentration.
Water always flows from areas of high water concentration to lower water concentration.

Basically the definition of osmosis is movement of water molecules from a region of higher water potential (In other words concentration) to a region of lower water potential through a partially-permeable membrane (membrane which onli allows certain substances 2 pass through). I think wat fireflywishes posted sounded quite logical :nerd: XP
