5% NaCl solution is unusually high. And because all living organisms seek to maintain an isotonic balance with their environment,osmotic diffusion will occur in order to re-establish this balance.Hence,there will be a diffusion down the gradient i.e. from the medium containing the NaCl solution,into the bacterial cell which has solutes dissolved in it but insufficient to even out this balance.The end result will then be lysis or bursting of the bacterial cell,as it gorges in the NaCl to maintain equilibrium.
0.85% nacl sol or normal saline solution is used as it is an isotonic solution which will emmulsify bacterial cells and dont cause any injury ( injury due to osmotic gradient in which cell can shrink or swell/burst ). solution upto 0.98% can be used.
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.
Roughly 0.564nm. It takes on a face-centered cubic structure.
Sodium hypochlorite bleach primarily targets the cell membrane of bacterial cells. This can disrupt the cell membrane's structure and function, leading to cell death. Additionally, sodium hypochlorite can also affect bacterial proteins and enzymes, further compromising the cell's ability to survive.
That depends entirely on what is in this solution. Hypotonic and hypertonic are relative terms to compare to solutions usually serperated by a semi-permeable membrane. Relative to a plant cell or e.g. a red blood cell the named solution of 0.3x10-5M NaCl is hypotonic, but compared to sea water it is hyper. A hypotonic solution contains a lesser concentration of impermeable solutes than the the inside cell. When a cell's cytoplasm is bathed in a hypotonic solution the water will be drawn out of the solution and into the cell by osmosis. If water molecules continue to diffuse into the cell, it will cause the cell to swell, up to the point that lysis (rupture) may occur.
When a bacterial cell is placed in a 10% NaCl solution with penicillin, the high salt concentration will cause water to leave the cell, leading to dehydration and shrinkage of the cell. The penicillin will inhibit the synthesis of the bacterial cell wall, making it more susceptible to the osmotic stress induced by the high salt concentration, ultimately leading to cell death.
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.
If a bacterial cell is placed in water by osmosis, water will move into the cell due to a lower concentration of solutes inside compared to the outside environment. This influx of water can cause the cell to swell and potentially burst if the cell wall is not strong enough to withstand the pressure, a process known as osmotic lysis.
Water leaves the cell, causing the cell to shrink.
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 a freshwater bacterial cell is placed in salt water, water will leave the cell due to the higher concentration of solutes in the surrounding salt water. This process is known as plasmolysis, and it can lead to the bacterial cell shriveling up and potentially dying due to dehydration.
protoplasm tends to shrink due to NaCl..causing it to dehydrate and pulling the water out of the cell..
water leaves the cell causeing the cell to shrink.
The cell expands/gets bigger.
The bacterial cell will undergo osmotic lysis due to the hypotonic environment created by the distilled water, causing water to enter the cell and potentially burst it. The presence of lysozyme will further damage the bacterial cell by breaking down its cell wall, making it more susceptible to lysis.
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.
Nothing. There would be no gradient between the cell and the solution.
