Osmotic pressure
Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in its pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane. Osmosis occurs when two solutions containing different concentrations of solute are separated by a selectively permeable membrane.
Collaborative consumption
Collaborative consumption is the set of those resource circulation systems in which consumers both "obtain" and "provide", temporarily or permanently, valuable resources or services through direct interaction with other consumers or through a mediator. It is sometimes paired with the concept of the "sharing economy". Collaborative consumption is not new; it has always existed (e.g. in the form of flea markets, swap meets, garage sales, car boot sales, and second-hand shops).
Turgor pressure
Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall. It is also called hydrostatic pressure, and is defined as the pressure in a fluid measured at a certain point within itself when at equilibrium. Generally, turgor pressure is caused by the osmotic flow of water and occurs in plants, fungi, and bacteria. The phenomenon is also observed in protists that have cell walls. This system is not seen in animal cells, as the absence of a cell wall would cause the cell to lyse when under too much pressure.
