The flow of water into a cell is called endomosis, and the flow of water out of a cell is called exomosis

When a living cell is palced in hypertonic solution, water moves out of the cell by exosmosis.
If a plasmolysed cell(the protoplasm of which has shrinked and left the cell wall) is placed in a hypotonic solution,water from outside enters the protoplasm or endosmosis occurs.

A quick search will help you...

Surface area affects osmosis because as the cell gets larger it has more needs. That doesn't mean that the surface area can supply it. As the cell gets larger the proportion of surface area to total volume gets higher and higher. This means that the amount of surface area is not large enough to move all the nutrients and water into the cell fast enough or out fast enough. This is why a cell divides into a smaller cell. It does it for its own survival.

Osmosis is the diffusion of water through a permeable membrane. It is only the diffusion of water and nothing else. As in how to test it do you want to know if a certain object is capable of osmosis or is occuring?
