Osmosis Notes (Biology)

Everyday examples of Osmosis:
The most common example of everyday osmosis is provided by plants and animals. Plants absorb water from the Earth through osmosis. The exchange of water in body fluids and cells in animals is also osmosis.

How does Osmosis affect Animal and Plant cells?
Plant cells have a cell wall made of cellulose, animal cells don't. The cell wall prevents the plant cell from bursting due to too much intake of water,. The plant cell also has a vacuole which most animal cells don't. When the osmotic gradient works against the plant cell water leaves it and the membrane pulls away from the cell wall, but it doesn't reduce in volume. When the osmotic gradient works to put water into the cell it ends up turgid and pushes against the cell wall, but rarely results in bursting of the plant cell. In the animal cell when the intake of water is too high it will burst as there's no cell wall to prevent this. When there is a great loss of water it will shrivel up (crenation) and will usually die.

What is Turgor pressure?
Turgor pressure is the outward pressure that occurs in a plant cell when the cytoplasm and vacuoles fill up with water and the cell membrane pushes against the cell wall. Basically, it's the pressure exerted by the water inside the cell against the cell wall.

The relation between Turgor pressure and Osmosis:
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.

Titanic: Diary Entry (English)

 "I was on the whale deck in the bow calling the watch that was to relieve when the ice first came aboard. The collision opened the seams below the water-line but did not even scratch the paint above the line. I know that because I was one of those who helped to make an examination over the side with a lantern. I went down into the engine-room at 12:40am. We even made coffee, so there was not much thought of danger. An hour later I was still working at the light engines. I heard the chief engineer tell one of his subordinates that number six bulkhead had given way. At that time things began to look bad… I was told to go up and see how things were, and made my way up a dummy funnel to the bridge deck. By that time all the boats had left the ship, yet everyone in the engine-room was at his post."

-Alfred White (A greaser in the engine-room), April 12th 1912.
