A cell is hypertonic when it has a greater concentration than its environment, but, when a solution is hypertonic, it has a greater concentration than the cell it is being compared to. For example, a 5% salt solution is hypertonic to an onion cell while the onion cell is hypotonic to the solution.
The salt concentration of an onion cell must be less than 5% - actually its somewhere between 1.6 and 1.3 percent.
This question should not be in genetics, but I don't feel like switching it.

In what ways is the action of an onion cell in HYPERTONIC solution similar to that of a red blood cell?
In a hypertonic solution, both onion cells and red blood cells experience osmosis, leading to water loss. As a result, the onion cells undergo plasmolysis, where the cell membrane pulls away from the rigid cell wall, while red blood cells undergo crenation, causing them to shrink and become distorted. In both cases, the cells are unable to maintain their normal shape and function due to the loss of water in response to the higher solute concentration outside the cells.
Why do onion cell plasmolyze?
Onion cells plasmolyze when placed in a hypertonic solution because water moves out of the cell, causing the central vacuole to shrink and the cell membrane to pull away from the cell wall. This occurs to balance the water concentration inside and outside the cell.
Why do we use NaCl in a plasmolysis of onion?
NaCl is used in plasmolysis of onion cells to create a hypertonic solution, causing water to move out of the cell and shrink the cell contents away from the cell wall. This helps in studying the structure of the cell membrane and cell wall under different conditions.
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 would most likely happen to an onion cell if it were placed in a liquid with a high concentration of solutes?
As the "salt solution" is a hypertonic solution which has the concentration of the solute outside of the cell is higher than the inside's. That also means the concentration of the water is now smaller in the outside of the cell than the inside's, which make the water molecules diffuse from the inside of the cell to the outside, resulted in making the cell (onion cell in this case) shrunken, or smaller.

What happen to onion cell epidermis if placed in hypertonic solution?
If an onion cell epidermis is placed in a hypertonic solution, water will move out of the cell due to osmosis, causing the cell to shrink and the cell membrane to pull away from the cell wall. This process is known as plasmolysis.

How did iodine solution affects the image of the onion cells?
Iodine solution stains the starch granules in the onion cells, making them appear darker under a microscope. This helps visualize the structure and distribution of the starch granules within the cells, providing information about the cellular organization of the onion tissue.

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.
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 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.
Where are onion cells found?
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
