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.

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...

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...
Diffusion and 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...
what would happen to a freshwater unicellular organism if it were suddenly released into a saltwater environment. Use the terms isotonic, hypotonic and hypertonic in the answer. (3 points)
What would happen if a marine organism were placed in freshwater? (3 points)
The results of the experiment 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...
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...
0M and 0.3M are said to be hypotonic solutions whereas the solutions of 0.5M and 0.7M are said to be hypertonic solutions (Biology Department, 2013). From Figure 1 it was determined that the osmolarity of the potato tissue was 0.335M, the value was obtained by interpolating the molarity at the...

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...
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...
, 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...
, hypotonic, or isotonic. We proved that when there is a greater percentage of sucrose in the bag the process is hypotonic. The diversity of it is hypertonic; where is has a low concentration of sucrose in the dialysis bag. It shows the bag lost weight, because the fluids leave the bag....
do the water will go from low concentration to a higher concentration in the potato.
5. Draw a diagram of a cell in a:
a. hypertonic environment;
b. isotonic environment;
c. hypotonic environment
6. What proof do you have that potatoes have that potatoes contain some salt? What is the...
, & Isotonic
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...
that plant cells, just like potato cells, don’t behave the same way as animal cells. They like hypotonic solutions and are not at their best in isotonic and hypertonic solutions (Campbell, 2010). If we look at the figure 1, the graph clearly shows that at 0M and 0.3M the solution is hypotonic which...
solution is hypotonic solution the cells try to bring it to isotonic solution for that they do the osmosis (by taking out water to the hypertonic solution) and that’s how they lose mass.
In the pure water the potato mass raised up because the cells got more water inside. This solution is hypotonic...
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...
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...

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...
causes the cell to shrivel. In a hypotonic solution, the solution has a low concentration of the solute, therefore when a cell is added to this solution water diffuses into the cell until it eventually lyses because it is over filled with water. When a solution is said to isotonic it means that...
