What happens when you put a potato strip in water?
The process that happens to both potato slices is called osmosis, which is a diffusion of water across the semipermeable membrane the potato slice cells possess. The water will diffuse into the cells of the potato, causing them to swell; the cells may be characterized as being “turgid”, or swollen.
What is the purpose of potato osmosis experiment?
Purpose: to find out the effect of osmosis on potatoes by placing potato chips in different strength sugar solutions. Hypothesis: that the potato chips will become soft and rubbery because their mass will decrease as they lose water in strong sugar solutions because of osmosis.
How does the potato affect the osmosis effect?
This osmosis effect is the flow of water across the semi permeable membrane from a solution of higher water potential (water) to one with a lower water potential (potato). The potato will allow water into it to even out the sugar concentration between the solution and the potato.
How do you make osmosis in potato strips?
Potato strips had to placed into the Petri dish with a concentrated solución. Cover the pieces with the solution CS. We had to pour the solution on the Petri dish and cover the potato strips. Place 2 pieces in the Petri dish labelled DW. We had to place the twovother remaining strips in the Petri dish. Cover with the solution DW.
How does hypotonic solution affect the weight of potato strips?
Lastly, the hypotonic solution is characterized by the low concentration of solute molecules and solvent molecules move from this solution to other regions that have high solute concentrations (Sperelakis, 2011). To determine the relationship between an increase in sucrose concentration and the resulting effect on the weight of potato strips.
How does osmosis occur in a CS solution?
We see this present in the experiment. The potato strips that were covered with the CS solution were in a concentrated solution, and this causes for osmosis to take place, water from the potato strip diffues through the partially permeable membrane to create a balance between high and loswater potentials.
Why does water leave potato strips by osmosis?
We have a hypotonic solution. At higher salt concentrations, however, we have a decrease in potato strip length. This tells us the water potential is higher inside of the potatoes, so water as left the potato strips by osmosis. We can say that the solutions are hypertonic to the potatoes.

How is the osmosis of a potato cell dependent?
It is dependent on temperature, size of the molecule, thinness of the membrane and the concentration gradient. In this activity, osmosis in potato cell was studied. Salty water with Cl- (aq) is concentrated as compared to the cell sap, that is, hypertonic solution.
