hypertonic, hypotonic or isotonic. My hypothesis for this experiment was that the 0.0 to 0.3 molarity solutions would be hypotonic to the potato tissue, the 0.4 molarity solution would be isotonic and the 0.5 & 0.6 molarity solutions would be hypertonic. If the sucrose solution increased then their...
Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount.
Hypothesis question: What will...
observe the effect of isotonic, hypotonic, and hypertonic solutions on potato cells.
Independent variable: Sucrose concentration
Dependent variable: Potato weight
I hypothesize that when the sucrose concentration is higher, the weight of the potato cylinders will decrease and when...
When the potato gains weight it was in a hypertonic solution, and when the potato loss weight it was in a hypotonic solution. If the potato would not have changed weight it would have been an isotonic solution, but that was not the case in this experiment. The potato either gained, or...

cells also show the same effects as the epidermal onion cells when placed in hypotonic, isotonic and hypertonic solutions.
In 10% (w/v) NaCl, the weight of potato sticks decreasing in large percentage around 16% - 13%. This shows the water in the cells moves out by osmosis to the extracellular...

what I observed, my hypothesis, stating that the potato will absorb more starch than the sweet potato, was correct.
2. Use your observations to explain if each type of cell (potato, sweet potato/pear/apple) was isotonic, hypertonic, or hypotonic to each of the solutions. Explain what happened to each...
osmotic pressure in a fluid compared to another fluid, as in a ‘hypotonic solution’ – compare: hypertonic and isotonic
➢ Having a higher osmotic pressure in a fluid relative to another fluid.
➢ Having the same (or equal...
gradient in different ways. In a hypertonic solution there is a higher concentration of the solute than in the other solution. Therefore, when the cell is put into a hypertonic solution, the water diffuses out of the cell which causes the cell to shrivel. In a hypotonic solution, the solution has a low...

The above graph is similar to that of Figure 1.3, but this has labeled which solutions were hypertonic to the potato cytoplasm, which were hypotonic, and which was isotonic.
As the concentration of the sugar increases, the more mass the potatoes would lose. This would make the...
referred to as dynamic equilibrium.
Solution A is hypertonic to the potato; the potato submerged in Solution A will weigh more than the potatoes in the hypo/isotonic solutions. Solution B is hypotonic to the potato, so the potato will weigh less comparatively. Solution C is...
of sports drinks: isotonic, hypotonic, and hypertonic. Isotonic sports drinks quickly replace fluids lost by sweating, and supply a boost of carbohydrates; they are also the choice for most athletes. For those athletes that replace fluids without the boost of carbohydrates, hypotonic drinks would be...
cell is in an environment that is hypertonic, the free water concentration is greater inside the cell while the solute concentration is higher outside. The net diffusion of water is out of the cell. In the case of a cell lacking a cell wall (animal cell), a hypertonic environment causes the cell to shrink...
Introduction Now, the goal of this lab was to find the osmotic potential of the potato cells. Each of the five solutions can either be hypotonic, hypertonic, or isotonic to the potato cell. If a solution is hypotonic, then water will flow into the cells causing the cells to expand and theturgor pressure...

How does the mass of a potato slice change when it is put into distilled water, tap water or salt water?
Background: In this lab we will find out how water with different concentrations affects the mass of a potato slice when the slice is soaked in the water. In this lab the effects of osmosis will...
we refer to an isotonic solution, which means there is not net movement of water crossing the membrane in animal cell while plant cell will tend to flaccid. (Brooker et al., 2010) If instead, the concentration outside the cell is higher than inside; we call those solutions hypertonic and are not ideal...
adjust to varying chemical concentrations in the environment and to observe the effect of isotonic, hypotonic and hypertonic solution on cells. I hypothesize that when the sucrose concentration will change, the mass will also change.
For this experiment, the following materials were used...
, we determined that the distilled water was the hypotonic solution and the salt water was the hypertonic solution and had a higher OAS. We determined that the preferred way of living for plant cells is in either an isotonic or hypotonic environment. In experiment 5.3 we determined that as the sucrose...
showed that the potatoes were affected by hypertonic and hypotonic osmosis. The potato in salt water decreased in its mass by hypertonic by at least 0.2 to 2%. The potato in regular water increased in it's mass by hypotonic by at least 0.6 to 4%. The potato represents a cell being affected by osmosis...

Tonicity refers to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic, hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A, Solution B, Solution C, and Solution D. Since...

Each piece in the solution reacted different. The sugar solution potato had the lowest mass , the boiled potato stay in the same mass and the potato that was in the...
losing mass. At the sucrose concentrations 0.2M and 0.3M we reached the point where the potato is at an isotonic environment, it would be between 4.02% to -3.26%.
Our results lead us to have significant difference.. The sucrose concentrations that are in a hypotonic and hypertonic solutions support...

respect to osmosis, animal cells, which do not have cell walls, absorb water from a hypotonic solution (concentration of solute lower than that found inside the cell) and will swell until they burst. In a hypertonic solution (concentration of solute higher than that found inside the cell), the animal...

Experiment 2 :
The purpose of doing this experiment is to determine the effects of isotonic, hypotonic, and hypertonic solutions to potato cells. From a brief opinion we can conclude the hypothesis ; the concentration of an external solution which is isotonic to the cell sap does not...

movement of water is referred to as osmotic pressure.
When potato tuber cells are placed in the sucrose solution of different concentration, there is an expected weight loss in solution of higher concentration (hypertonic solution) or weight gain in solution of less concentration (hypotonic...
