But because of such high molars of sucrose, the water can diffuse all the way, throughout the two substances, equalling the concentration gradient of the two substances. My theory in this experiment is that, due to the difference in the water concentrations of the two substances, I believe that the weight of the potato will start decreasing when it is tested on 0.2 molar solutions of sucrose and greater. By researching information about osmosis, and making predictions of the results, I believe the graph would look something like this: Fair Test Fair testing should play a big part in this experiment. If this experiment isn�t a fair test, we will be obtaining the wrong results, which could lead us to the wrong conclusions. First of all, and most importantly, we will have to get the measurements and the weights of the solutions and the potatoes as exact, and as accurate as possible. We will try and get the measurements of the potatoes as accurate as possible for every single potato, evenly cutting the potato pieces, and making a record of the length to the nearest millimetre. And we will be using a very sensitive balance so that we can get the best readings possible. ...read more.

    When plant cells are placed in concentrated sugar solutions they lose water by osmosis and they become flaccid. This is the exact opposite of "turgid". The contents of the potato cells shrinks and pulls away from the cell wall. These cells are said to be plasmolysed.

  2. My main aim in this experiment is to find out if osmosis occurs in ...

    This is because there isn�t much difference between the two substances. I believe that the weight and the size of the potato won�t be altered much. The 0.4 molar solutions of sucrose, similar to the 0.2 molar solution of sucrose, compared to the potato, both substances have very close concentration gradients.

    The potato tissues, being surrounded by a weak solution, will be most likely to swell up and become turgid, taking in all the water it can possibly take in. With the potato in molar solutions of sucrose, I don�t think there will be much change in the weight of the potato.

    With both of these sources, the potato will keep on working, until it dies of either lack of water, too much water. When the concentration gradient is lower in the potato, the water will transfer from the solution to the potato.
