What is the relationship between osmosis and turgor pressure? | Yahoo Answers
Turgor pressure is the hydrostatic pressure in excess of ambient atmospheric pressure; osmosis; plasma membrane; solute; stress; turgor; water potential. The water pressure inside plant cells is called turgor pressure, and it is maintained by a process called osmosis. Technically speaking, osmosis is the movement. Relationship between osmosis and turgor pressure. Osmosis, being the diffusion of water, is the main way that plants can increase or decrease their turgor.
Plant cells maintain a delicate balance of water and various dissolved salts and sugars. If the fluid inside the plant cell is "saltier" than the surrounding fluid, water molecules move in to try to reach equilibrium.Turgor Pressure I Lab Experiment I Flip Learning I Science Alon
If there were no cell membrane, then at the same time the salty water would diffuse out, until the salt concentrations inside and outside the cell were equal. Osmosis These rigid, stacked "boxes" keep the plant upright.
If the "balloons" deflate, then the boxes collapse. Plants must maintain their internal water pressure, or turgor pressure, to keep stems rigid and leaves expanded to the sunlight. This means that water must be available to the plant whenever it needs it.
So, next time you have a dry spell, and are commiserating with your gardening friends, you might just say, "Boy, the soil is dry as a bone.

For instance, if the fluid inside a cell has a higher osmolarity, concentration of solute, than the surrounding fluid, the cell interior is hypertonic to the surrounding fluid, and the surrounding fluid is hypotonic to the cell interior. Tonicity in living systems If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane.
There is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Mariana Ruiz Villareal In the case of a red blood cell, isotonic conditions are ideal, and your body has homeostatic stability-maintaining systems to ensure these conditions stay constant.
What is the relationship between osmosis and turgor pressure?
If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die. In the case of a plant cell, however, a hypotonic extracellular solution is actually ideal. The plasma membrane can only expand to the limit of the rigid cell wall, so the cell won't burst, or lyse. In fact, the cytoplasm in plants is generally a bit hypertonic to the cellular environment, and water will enter a cell until its internal pressure—turgor pressure—prevents further influx.
Maintaining this balance of water and solutes is very important to the health of the plant.
Turgor pressure - Wikipedia
If a plant is not watered, the extracellular fluid will become isotonic or hypertonic, causing water to leave the plant's cells.
Owing to osmosis, the solutes drive net water uptake into the cell, and turgor pressure builds up. Scheme which quantifies processes involved in turgor generation. The same applies to the distilled water in which the cell is bathed. The result is a cell turgor of 0.
