what is the relationship between osmosis and turgor pressure?

Question

anonymous · Answer

Turgor Pressure is the pressure in plants created by either an excess or lack of water. Osmosis, being the diffusion of water, is the main way that plants can increase or decrease their Turgor pressure.

Turgor pressure is the pressure in plants created by either an excess or lack of water. If there is lots of water and the cell membrane is bulging to the max, then the cell is turgid. If there is very little water and the cell membrane is shrinking away, then the cell is flaccid. Osmosis, being the diffusion of water, is the main way that plants can increase or decrease their turgor pressure. Turgor pressure will increase if the solution outside the cell is HYPOTONIC, meaning that the solute concentration outside the cell is lower than inside (like distilled water surrounding a cell). Turgor pressure will decrease if the solution outside the cell is HYPERTONIC, meaning that the solute concentration outside the cell is higher than inside (like salt water surrounding a cell). Plasmolysis is just when a plant cell's membrane shrinks away from the cell wall and causes it to shrivel. http://answers.yahoo.com/question/index?qid=20101102140843AA23REp

Plant cells are surrounded by rigid cellulose walls, they take in water by osmosis when placed in pure water. Turgor Pressure is the pressure in plants created by either an excess or lack of water. Osmosis, being the diffusion of water, is the main way that plants can increase or decrease their Turgor pressure.
