of the potatoes would be higher thus encouraging water to move into the potatoes and increase their mass. In other words‚ osmosis (diffusion of water from high to low concentration across a membrane) occurred and moved water from the environment hypotonic to the carrot into the carrot itself in an attempt to equalize concentration between them. In the higher molarity sucrose solutions‚ water’s potential is higher inside the potatoes—the water content of the carrots is more pure than in the outside

In this investigation‚ we are testing how concentration effects the rate of osmosis Hypothesis: The more hypertonic potato pieces are to a saline solution‚ the more weight the potato will gain. However‚ the potato pieces will decrease in weight when they are placed in a hypotonic solution. Dependent variables: • Change in mass of pieces of potatoes. Independent variables: • solutions sucrose concentrations. Controlled variables:

inside and outside of the egg is equilibrium. It has a situation where we can say that Hypotonic occurred‚ because the water moved into the egg. The egg placed in the syrup solution loss 38% of it’s weight. Fructose is a concentration gradient and it diffuse‚ so the water gets out of the egg till the concentration outside and inside of the egg is equilibrium. It has a situation where we can say that Hypertonic occurred‚ because the water moved out of the egg. The egg in the distilled water gained
