How is osmosis a part of a cell's overall function

[From: ] [author: ] [Date: 13-03-13] [Hit: ]

Molecules move across the plasma membrane from an area of low concentration to an area of high concentration-80% or more of a cells contents consists of water, and water is the primary medium in which all cellular metabolism occurs. Since osmosis is defined as the diffusion of water across membranes, such as the cell membrane, it is therefore the primary means by which the water contents of a cell is regulated. And the answer to your true/false question is false; molecules flow from HIGH TO LOW concentration.......

Also, is this true or false?:
