What structures protect plant and bacteria cells from potential damage resulting from osmotic pressure?

A plant or bacteria cell's cell wall is a tough and flexible outer layer that supports and protects the cell. It protects cells from over-expansion when a solvent like water enters the cell during osmosis.

The cell wall because it is semi-rigid, will only allow the cell to expand to a limited size and any excess water that could cause osmotic rupture would be "taken out of the cell". Animal cells do not have cell walls but some organism have contractile vacuoles that "pump out" excess water from the cell.

It is also the cell wall that prevents it from bursting.

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 is the meaning mm Aq?
It is a measure of pressure - measured as the height (in millimetres, mm) of water (Aqua) that the pressure would support.
Do bacteria cell walls have peptidoglycan?
Yes, bacteria walls have peptidoglycan. Peptidoglycan is that target for antibiotics like penicillin, which prevent the cell wall formation. This causes the bacteria to burst with turgor pressure.

What is matric potential?
Matric potential is the sum of: Osmotic Potential(φs) + Hydrostatic Pressure(φp). Matric potential useful because there are some situations where it is difficult to distinguish between the measurements of Osmotic Potential(φs) and Hydrostatic Pressure(φp).
How do natural rocks structures form?

Which factors affect water potential in living cells?
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.

Do bacteria cause hypertension?
Oh no Bacteria do not cause high blood pressure. High blood pressure is "your body going at war with itself" (sort to speak) There is no bacteria nor viruses nor parasite involved
