What else can I help you with?
Is osmosis controlled by a cell nucleus?
No, osmosis is not controlled by a cell nucleus. It is a passive event controlled by the amount of water on one side of a membrane compared to the water on the other side of a membrane. Water will always move from a high concentration of water to a lower concentration of water.
What is the name for the movement of water across the plasma membrane?
The movement of water across the plasma membrane is called osmosis. It occurs in response to concentration differences of solutes on either side of the membrane.
Which side of a selectively permeable membrane does osmosis exert a pressure?
It exerts pressure on the side with a higher concentration of water.
The equal movement of water from either side of a semipermeable membrane is known as what?
The movement of of a solute like water is called osmosis.
Why does the presence of dissolved particles on one side of a membrane ressults in diffusion of wager across the memebrane?
Addition of a polar solute lowers the water potential on that side of the membrane and so water will diffuse from the other side of the membrane from a relatively high water potential to the lower water potential, by osmosis.
The side from which more water molecules cross the semipermeable membrane?
The pure solvent side is the side from which more water molecules cross the semipermeable membrane.
Why does the addition of a solute with polar molecules to one side of a membrane result in diffusion of water?
Addition of a polar solute lowers the water potential on that side of the membrane and so water will diffuse from the other side of the membrane from a relatively high water potential to the lower water potential, by osmosis.
Did water diffused into or out of the dialysis membrane?
Water typically diffuses through the dialysis membrane depending on the concentration gradient. If the concentration of solutes is higher on one side of the membrane, water will move out of that side to the side with lower solute concentration, a process known as osmosis. Conversely, if the solute concentration is higher on the opposite side, water will diffuse into that side. Thus, the direction of water movement through the dialysis membrane is influenced by the relative solute concentrations on either side.
where does osmosis move water from when water is lost but electrolytes are retained?
Osmosis moves a solvent (eg water) to balance the concentrations of solute either side of a semipermeable membrane. The solvent is not lost.If the concentration of a solution is higher on one side of the membrane than the other, then the water moves across the membrane from the less concentrated side to the more concentrated side to dilute it until the concentrations on either side are equal..
How does water move in osmosis?
Osmosis moves a solvent (eg water) to balance the concentrations of solute either side of a semipermeable membrane. The solvent is not lost.If the concentration of a solution is higher on one side of the membrane than the other, then the water moves across the membrane from the less concentrated side to the more concentrated side to dilute it until the concentrations on either side are equal.
Why did the number of the water molecules on each side of the membrane change where as the number of sugar molecules stayed the same?
The membrane is permeable to water but not to sugar.
When will water and solutes stop moving across a membrane?
Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.
What part of the cell membrane attracts water molecules?
The hydrophilic heads of phospholipids in the cell membrane attract water molecules. These heads have a charge that interacts with the polar water molecules, allowing them to form hydrogen bonds with the water. This hydrophilic property helps create a stable structure for the cell membrane.
Osmosis in real life?
Osmosis certainly does happen regularly in real life. Osmosis is the transportation of water from one side of a membrane to the other side of a membrane.
Is osmosis controlled by a cell nucleus?
No, osmosis is not controlled by a cell nucleus. It is a passive event controlled by the amount of water on one side of a membrane compared to the water on the other side of a membrane. Water will always move from a high concentration of water to a lower concentration of water.
Why the water molecules involves in osmosis?
Water molecules are involved in osmosis because they can move across a semi-permeable membrane to equalize the concentration of solutes on either side of the membrane. This movement of water is driven by the concentration gradient of solutes, resulting in changes in the volume of the compartments on either side of the membrane.
Are the salt particles able to cross the membrane?
If you are referring to osmosis, the salt doesn't cross the membrane, water does. Water will move into the salt water to attempt to dilute it to create homeostatsis, or equal concentrations on each side of the membrane.
