This depends on the nature of the NaCl solution...
If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;
so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).
The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;
The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
If a red blood cell is placed in a 50% NaCl solution, the cell will undergo a process called crenation, where water leaves the cell due to the high concentration of salt outside. This causes the cell to shrink and lose its normal shape, which can ultimately lead to cell damage or death.

A 0.3% NaCl solution is isotonic, meaning it has the same osmotic pressure as red blood cells. When red blood cells are placed in a 0.3% NaCl solution, there is no net movement of water in or out of the cells, resulting in no change in cell volume. This solution is often used in laboratory settings to maintain the integrity of red blood cells for experiments or storage.
When placed in a 5% NaCl solution, a bacterial cell will likely experience water loss through osmosis due to the high salt concentration outside the cell. This will cause the cell to shrink and may lead to dehydration and cell death if the salt concentration is too high.
I did this experiment and after a while the onion cell became incredibly easier to see.
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.
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.
A hypotonic solution of NaCl has a lower concentration of salt (NaCl) compared to the concentration of salt inside a cell. When a cell is placed in a hypotonic NaCl solution, water will move into the cell, causing it to swell, potentially leading to cell lysis if the cell cannot regulate its volume adequately.
In a 10% NaCl solution, which is a strong hypertonic solution, red blood cells would shrink and shrivel up due to the high concentration of salt outside the cell causing water to move out of the cell through osmosis, leading to cell dehydration and eventual cell death.
If a red blood cell is placed in a 50% NaCl solution, the cell will undergo a process called crenation, where water leaves the cell due to the high concentration of salt outside. This causes the cell to shrink and lose its normal shape, which can ultimately lead to cell damage or death.
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.
protoplasm tends to shrink due to NaCl..causing it to dehydrate and pulling the water out of the cell..
In a hypotonic environment, an onion cell will fill up with water. Hypotonic refers to a solution that has lower osmotic pressure than the solution you're comparing it to.
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.
When a red onion cell is placed in a sucrose solution, water from inside the cell will move out due to osmosis. This will cause the cell to shrink and lose its turgidity as water moves from an area of higher concentration to lower concentration (from inside the cell to the solution outside).
becuse of the lodine solution
one solute is Logols Solution. I think!
