What happens when you put potato strips 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 was the purpose of the potato experiment?

Potato Lab The Purpose of the Potato Lab was to see how salt water will affect your cells. The example used was, if a person was stranded in the middle of the ocean with no fresh water, would the salt water hydrate them?

What is the water potential of a potato?

Water potential explained in simpler terms is the measure of water’s potential to perform work. So, the water potential of potato tissues is 0.25.

What would happen to the water potential of a potato if left to dehydrate in the open air?

If the potato is allowed to dehydrate by sitting out in the open air the water potential would decrease (be more negative) because the concentration of solutes within the cells would increase as potato cells dehydrate. Therefore, the osmotic pressure and water potential both decrease.

What is the water potential of a potato cell at equilibrium?

Explain your answer. There will be no movement. The two solutions will be at equilibrium when the water potential is equal (zero); the solute concentrations do not have to be the same.

Why does osmosis take place in potato strips?

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. Causing the strip to shrink and become softer and flaccid.

Why do potatoes shrink in a salt water solution?

The opposite is the case in the higher concentration salt solutions. If the salt concentration in the cup is higher than inside the potato cells, water moves out of the potato into the cup. This leads to shrinkage of the potato cells, which explains why the potato strips get smaller in length and diameter.

Why does a potato strip increase in mass?

In order to avoid potential flaws, next time the experiment should be measured precisely, be timed and use distilled water. The following results and conclusions were deduced by this experiment: An increase in mass of the potato strip due to the movement of water molecules into the plant cells via osmosis.

Why does Ribena make a potato strip shrink?

Ribena is mainly a sugary solution and hence is hypertonic to the potato cells, which are hypotonic. The water molecules will move along their concentration gradient out of the cells and thus make the potato strip shrink. The decrease in the number of water molecules results in loss of volume and length.
