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 else can I help you with?
What happens to a cell that is placed in a hypertonic hypotonic and isotonic environment?
An Animal Cell in hypertonic solution will look shriveled due to osmotic effects on the cell. the hypertonic solution means there is more water potential outside of the cell, water moves from a low water potential to a high water potential. Therefore the water diffuses out of the cell decreasing the volume bringing the cell membrane in making it look shriveled up.
What happens when you submerge a plant cell and an animal cell in solutions with different water potential?
They both will eventually burst.
Which has more water potential a 0.6 molar solution or a 0.4 molar solution?
The 0.4 molar solution has a higher water potential because as the concentration of solute decreases, water potential increases. Water potential is a measure of the tendency of water to move from one area to another, and it is affected by factors like solute concentration and pressure.
Under what conditions will an animal cell burst?
When surrounded by a hypotonic solution (i.e. a solution that has a water potential higher than that of the cell itself, such as pure water). Water moves into the cell by osmosis. The cell cannot withstand this pressure and will burst, a process known as haemolysis.
What happens when water moves out of a cell if the cell is placed in a what solution?
Hypotonic Solution

What happens to a animal cell when placed in an hypertonic solution?
In a hypertonic solution water is most likely to move out of the cell because it is in a high concentration and the cell will shrink. They tend to give up water across the permiable cell membrane

They both will eventually burst.
What happens to red blood cells when they are placed in the solution that has higher water potential?
they absorb water through the permeable membrane and on ovr absorbing...they burst up
What happens to a animal cell when in a hypertonic solution?
A hypertonic solution is less concentrated compared to the cytoplasm of the animal cell. When an animal cell is placed in a hypertonic solution, water diffuses across the selectively permeable cell membrane in an attempt to form an equilibrium between the two liquids. If the solution is hypertonic enough compared to the cell's cytoplasm, the cell would swell and could possibly explode.
What facts about osmosis?
Osmosis is the process where Water Molecules move from a solution with a Higher Water Potential to a solution with a Lower Water Potential through a Partially Permeable Membrane.
What is the new water potential of a plant cell of water potential 500kPa after immerse into pure water?
Water potential is the potential energy of water in a system (eg a solution or a cell) compared with pure water under the same conditions. The value of the water potential depends mainly on two factors: 1) The presence of dissolved solutes. Solutes dissolved in the water reduce the energy of the water molecules, and so lower the water potential. This happens because the solute molecules attract the water molecules and reduce their movement. The component of water potential due to solutes is called the solute potential of the solution. 2) The presence of an excess pressure, above that of normal atmospheric pressure. Pressure increases the movement of the water molecules and so increases their energy, thus increasing the water potential. The component of water potential due to pressure is called the pressure potential of the solution. The total water potential of a solution is the sum of the solute potential and pressure potential water potential = solute potential + pressure potential The pressure potential can be positive or negative. An additional pressure on the solution will be positive and increase the pressure potential. If the solution is subject to a reduced pressure (a negative pressure or suction) the pressure potential will be negative and will reduce the water potential. The solute potential is always negative and so always reduces the water potential. Pure water is given a water potential of zero (similar to the way in which the freezing point of water is given a value of 0o Celsius). So anything which reduces the energy of the water molecules (such as dissolving a solute) will reduce the water potential to below zero, and so will be negative. The movement of water depends on the difference in water potential between two systems eg two adjacent cells, or a cell and the surrounding solution. This difference is called the water potential gradient. Water will always move from the higher to the lower water potential ie down the water potential gradient. In osmosis, the two solutions involved are often at atmospheric pressure. In this case it is only the difference in solute concentration which determines the direction of water movement. Water moves from the dilute solution to the concentrated solution. The concentrated solution has a higher concentration of dissolved particles, and so has a lower solute potential than the dilute solution. Since the pressure potential is zero (no excess pressure), the water potential is equal to the solute potential. Water will therefore move from the higher water potential (ie the dilute solution) to the lower water potential (ie the more concentrated solution), down the water potential gradient. It is possible for the pressure potential to counteract the solute potential. For example, if a solute (eg salt) is added to pure water, the water potential will be reduced to a negative value. If the solution is then put under extra pressure eg in a syringe, the positive pressure potential can raise the total water potential above zero ie give it a positive value. This happens especially in plant cells, where the cell wall prevents an increase in volume of the cell. So if water enters by osmosis the extra water molecules cause the pressure inside the cell to increase. This intracellular pressure in a plant cell is called the turgor pressure.

What happens to potato strip in dilute water?
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.

What happens to a solution when a metal dissolves in water?
the solution becomes basic
Do a solution containing many molecules of dissolved sugar and amino acids have a high or a low water potential?
A solution containing many molecules of dissolved sugar and amino acids will have a low water potential. This is because the presence of solutes in the solution decreases the free energy of water molecules, making it less likely for water to move into the solution through osmosis. Water potential is determined by the concentration of solutes in a solution, with higher solute concentrations resulting in lower water potential.
