Worksheet to accompany Passive Transport Lab1.Passive transport requires ATP. True or False
2.Active transport requires ATP.
3.Water is pretty much a special case and can always travel through the cell membrane. True or
4.The cell membrane allows only some things to enter and only some things to leave, a property that makes it partiallypermeable.5.The movement of water across a cell’s membrane is called diffusion osmosis6.When water is in equilibrium across a membrane, the solution are said to be iso-tonic to each other. 7.Recall: Solution = solute + solvent. Our solvent here is water. The solute can be any of the things dissolved in our body. A key to understanding osmosis is actually reversing its definition. Instead of talking about water’s concentration gradient at first, look at the concentration gradient of the solute. (If you are good at math this will seem intuitive as it is just a ratio we are investigating: Amount solute/volume of water.)
