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.
How will the cells in an onion membrane respond to pure water?
The cells in an onion membrane will absorb the pure water through the process of osmosis. This will cause the cells to swell and become turgid as water enters them. Ultimately, the onion membrane may appear plump and rigid due to the increased water uptake.
Why does onion DNA get extracted?
Onion DNA is extracted for various purposes such as genetic research, molecular biology experiments, and forensic analysis. By isolating and studying onion DNA, scientists can better understand the genetic makeup of onions and use this information to improve onion crops, develop new varieties, and study genetic traits.
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).
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.

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?
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 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.
How will the cells in an onion membrane respond to pure water?
The cells in an onion membrane will absorb the pure water through the process of osmosis. This will cause the cells to swell and become turgid as water enters them. Ultimately, the onion membrane may appear plump and rigid due to the increased water uptake.
Where can you find onion epidermal cells and what is their significance in plant biology?
Onion epidermal cells can be found in the thin, transparent layer on the surface of an onion bulb. These cells are significant in plant biology because they are commonly used in science experiments to study cell structure, division, and function. They are also used to observe processes such as osmosis and plasmolysis.
