Sample Text:
Osmosis is the process by which water molecules pass through a semi-permeable membrane from a far less concentrated solution into a more concentrated solution, or vice versa. The specific aspect of potatoes that will be tested is the cell membrane. Cell membranes act as barriers to most, but not all molecules. Some materials are able to pass through these semi-permeable barriers that separate the inner (internal) and outer (external) environments, and as the source is inside the cell, the concentration gradient is constantly and consistently being re-elevated to attempt reaching equilibrium. This study is to prove the reason why osmosis and dialysis ...

HSC - Year 11 - Biology

Many molecules move in and out of a cell, and to control the movement of molecules that enter or exit, to and from the cell is the function of a semi – permeable cell membrane. It forms the boundary between the cytoplasm and the environment outside the cell. The movement of molecules in and out of the cell can be looked at as two different transportation techniques; Passive transport or Active transport. Passive transport is the movement of molecules (such as gases and water) into and out of the cell without the expenditure of energy whereas active transport is the movement of molecules (such as sucrose) into and out of the cell with the expenditure of energy
