What is an osmotically active substance?
It is a solute that causes osmosis to occur. For instance, if a solution contains sucrose and the membrane is impermeable to sucrose,, water will move out of the cell and into the solution to dilute it. Hence the solution is hypertonic. Sucrose would be considered an osmotically active solution in this case because it induces osmosis of water across a membrane.
What is a plasmolysed cell?
A plasmolysed cell is where the cell membrane has pulled away from the cell wall, resulting in the collapse of the cell. This usually occurs because the cell has been placed in a solution with a concentration of water lower then that inside the cell so the water has diffused through the semi-permeable membrane of the cell into the solution and the cell shrivels because it has no water.
What kind of solution causes the cell to shrink?
salt water. this will cause the cell to lose it's water osmotically resulting in it becoming plasmolysedA hypertonic solution
How does the cell membrane control water balance in the cell?
Osmosis, which is the movement of water across a semi-permeable membrane from where it is in high concentration to where it is in lower concentration. The purpose of osmosis is to equalize the concentration of solutes inside a cell and outside a cell.
Which way is water moving when a cell is placed in a hypertonic solution?
Water will move into the stronger solution (the one with the higher concentration of solute or solutes). For osmosisto occur, there must be a semi-permeable membrane (also called a selectively permeable or differentially permeable membrane). In all cells the plasma membrane is just such a membrane, and in mature plant cells there is another such membrane, the vacuolar membrane or tonoplast, surrounding the central vacuole.You can think of all solutes as attracting water. In a liquid containing one or more solutes, the total force attracting water is the osmotic pressure. When a semi-permeable membrane separates two solutions of differing osmotic pressures, there will be a net flow of water into the hypertonic (stronger) solution, in other words, the one with the higher osmotic pressure.Osmosis is passive, and involves a net flow because some water molecules move one way across the membrane, some the other.If the fluid surrounding a cell is hypotonic to the cytosol, that is another way of saying that the cytosol is hypertonic to the surrounding fluid. Either way, water will move into the cell.
What solution causes water to move out of a cell?
A hypotonic solution causes water to move into the cell. To further elaborate, a hypotonic solution has higher water potential and less solutes as compared to inside the cell. Bear in mind that osmosis is the movement of water from a region of high water potential to a region of low water potential. Therefore, this causes water to move into the cell. I hope this will be helpful!:)
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).

Net movement of water across a cell membrane occurs?
from a hypotonic solution to a hypertonic solution.
What happens to animal cell in a solution with high water potential?
Animal cells lack rigid cell wall. When an animal cell is placed in a solution with high water potential, the wanter enters the cell as cell membrane is freely permeable to water. As a result of continuously increasing water potential inside the cell, Cell membrane bursts and the cell is said to be lysed.
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.
What characteristics of a water molecule causes its attraction to a cell membrane?
Water molecules are polar This causes them to be attracted to the cell surface, which is also polar in nature

If a cell contains 97 percent water is placed into a 30 percent sugar solution what will happen to the cell?
The sugar solution is a hypertonic solution so water from the inside will exit through the cell membrane via osmosis and the cell will shrivel
How does the cell membrane control water balance in the cell?
Osmosis, which is the movement of water across a semi-permeable membrane from where it is in high concentration to where it is in lower concentration. The purpose of osmosis is to equalize the concentration of solutes inside a cell and outside a cell.
