What are the limitations or potential sources of error in osmosis in red onion cell experiment?
In an osmosis experiment using red onion cells, potential sources of error include inconsistencies in the concentration of the solution used, which can affect the rate of osmosis. Additionally, variations in the thickness and condition of the onion slices may impact the results, as well as the time allowed for osmosis to occur. Environmental factors such as temperature and light exposure can also influence osmotic activity, leading to unreliable data. Finally, human error in measurement or observation can further compromise the experiment's accuracy.
What is the effect of saltwater on onion cells?
If the concentration of salt is higher OUTSIDE the cell, then water will move from the cell to the outside (osmosis) to equilibrate the concentration gradient that you have created! Water will leave the cell, and the cell will shrink (due to the decrease in volume).
What will be your dependent variable in this experiment My experiment is does chilling an onion before cutting prevent you from crying I put three onions in the freezer refrigerator and kitchen?
The dependent variable in this experiment would be the amount of crying produced by cutting each onion, measured in tears shed or self-reported discomfort levels. The chilling method (freezer, refrigerator, kitchen) would be the independent variable being tested to observe its impact on reducing tears while cutting the onion.
What happens if instead of salt water you use distilled water in the red onion experiment?
If distilled water is used instead of salt water in the red onion experiment to observe osmosis, there would be no osmotic movement because distilled water does not contain any dissolved solutes. In contrast to salt water, where water moves from an area of low solute concentration to an area of high solute concentration, in distilled water there are no solutes to create a concentration gradient for water to move across the membrane.
What happens when you put an onion in salt water?
When you put an onion in salt water, the salt creates a hypertonic environment, causing water to move out of the onion cells through osmosis. This process results in the onion becoming limp and releasing some of its natural juices into the water. Additionally, the salt can enhance the flavor of the onion while also drawing out some of its moisture. Over time, this can lead to a brined effect, making the onion more flavorful.

Why use onions in a demonstration of osmosis?
Onions are commonly used in osmosis demonstrations because they have cell walls that allow water to pass through. By placing an onion slice in a hypertonic solution, like salt water, you can observe osmosis in action as water moves out of the onion cells, causing them to shrink and wrinkle. This helps to illustrate the concept of osmosis effectively.
What will happen if you put onion skin cell into 10 percent sugar solution?
If you place an onion skin cell into a 10 percent sugar solution, water will flow out of the cell via osmosis due to the higher concentration of sugar outside the cell. This will cause the cell to shrink and undergo plasmolysis as it loses water and shrivels up.
What will happen if onion peel is kept in strong sugar solution?
The onion peel will shrink and dehydrate due to osmosis. The strong sugar solution will draw the water out of the onion cells, causing them to lose water and shrink in size.

Which parts of the onion cells stood out the most after they were stained?
Only you know that because you did the experiment not us.
Can onion make a guinea pig get diarrhea?
Onion might kill it. Onion will kill cats and not good for dogs either. Why are you feeding it onions?

Can you cook with the onions from onion grass?
You can cook the onions from onion grass but you might want to rinse it off.
What would happen if you added three drops of iodine to an onion?
I did this experiment and after a while the onion cell became incredibly easier to see.
