Turgor is described as the formation of sclerotic tissue inside the lumen?
1) The state of being turgid; the rigid or fullness state of a cell due to high water content as a result of differing solute concentrations between a semipermeable membrane. (2) The pressure produced by a solution against the semipermeable membrane enclosing the cell due to osmotic pressure differences between the inside and outside of the cell.
Why does the level of a more concentrated solution rise when two solutions of different concentrations are separated by a semipermeable membrane and when does it stop rising?
The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.
What causes osmotic pressure to develop in a cell?
Osmotic pressure occurs when two solutions of different concentrations are separated by a semi-permeable membrane. Often the solute cannot move through the membrane, so there is pressure for the water to move from the less concentrated side to the more concentrated side, to dilute it.
What is the effect of hypertonic solution on rbc?
A blood cell immersed in a hypertonic solution will cause water to move out of the cell, thereby causing it to shrivel. Osmotic pressure is water's tendency to seek to equalize its own concentration across a semipermeable membrane (like the cell membrane of a blood cell). So in a hypertonic solution (relative to the solution inside the blood cell), there are less particles of water per particle of solute. This means the water concentration inside the blood cell is higher, and mother nature will have none of that. So water will move out of the cell, seeking to equalize its concentration across the cell membrane. If the membrane is also permeable to solutes in the hypotonic solution, they will move across the membrane following their own chemical and electromagnetic concentration gradients.
Which side of a selectively permeable membrane does osmosis exert a pressure?
It exerts pressure on the side with a higher concentration of water.
When the osmotic pressure is the same on both side's of a semipermeable membrane each solution is said to be?
Isotonic solution.
What is the name of the pressure that must be exerted on a solution to prevent the passage of solvent molecules into a solution when the solution and solvent are separated by a semipermeable membrane?
Osmosis.
The pressure needed to stop osmosis is called?
The osmotic pressure. This is the pressure which would have to be applied to a solution to stop water entering if it was separated from pure water by a semipermeable membrane.
What is the difference between waterpotential and diffusion pressure deficit?
Water potentialrefersto the power of to move from oneregionto another region where as DPD is thesuction ability of a cell or solution separated by semipermeable membrane.

How does osmosis happen?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane
Where and when does osmosis occur?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
What is the term of diffusion of water across a semipermeable membrane?
The term for the diffusion of water across a semipermeable membrane is osmosis. Osmosis is when the molecules of a solvent move from a less concentrated solution to a more concentrated one. This equalizes the concentrations on each side of the member.
Solution that causes cells to lose water?
It's the hypertonic solution. It contains a higher osmole concentration than the fluid present inside the cell "the cytosol" ,so the water inside the cells comes out in order to dilute the hyper-tonic solution in an attempt to make a balance between the two sides of the semipermeable membrane ( The cell membrane is a semipermeable membrane that separate the fluid present inside the cell and that outside it).
What does osmosis do in a cell?
the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.
What is the of definition omasis and an exsample?
movement of a solvent (as water) through a semipermeable membrane (as a living cell) into a solution of higher solute concentration that tends to equilize the concentration of solute on the two sides of the membrane.
