What is osmotic potential?
Osmotic potential is defined as the ability of a solution to suck water in if it was separated from another solution by a semi-permeable (meaning water gets through, but not the solution) membrane. This means that if you have pure water next to salt water, separated by such a membrane, the pure water would run over to the saltwater, while the water in the saltwater would stay where it is. Water, then, always moves towards a higher concentration, from high pressure to low pressure. This is also how trees get water from the roots up to the canopy, as they don't have beating heart like we do. The plants use their osmotic potential to transport water through the cells from the bottom (roots) where the osmotic pressure is high, to the top (canopy) where the osmotic pressure is low. As the water is transported up, the osmotic pressure in the roots sinks, allowing more water to run in from the soil.

How do you calculate solute potential?
ability of a medium to attract water molecules is known as osmotic potential. you may also label it as osmotic potential. at a time a system has more water potential and low solute potential and vice versa.
What does the vacuole do in the cell of a plant?
It maintains the osmotic potential of the cell
Is it good to grow plants in distilled water?
no. all things being equal and if the nutrients in the soil did not interact with the distilled water then distilled water has a lower osmotic potential than the cell sap in the roots; this would result in reverse osmosis from the roots (higher osmotic potential) to the soil (lower osmotic potential).
Is solute potential same as osmotic potential?
Yes, solute potential and osmotic potential are the same. Both terms refer to the effect of solute concentration on the movement of water into or out of a cell or solution. They are both influenced by the number of solute particles present in a solution.
How does osmotic potential affect diffusion?
Osmotic potential influences the movement of water molecules across a semi-permeable membrane. When there is a difference in osmotic potential between two solutions separated by a membrane, water will move from the area of lower solute concentration (higher water potential) to the area of higher solute concentration (lower water potential) to balance the concentrations. This affects the rate and direction of diffusion of solutes in and out of cells.
Why do you measure root pressure?
To take note of osmotic potential of cells in that root
Why is root-hair one-celled?
Because it perfoms absorption of water regulated by its osmotic potential
Do plant cells have a larger vacuole than animal cells?
To maintain high osmotic potential

Iso-osmotic or isosmotic
What does salts serve in cells?
Osmotic pressure. Trans-membrane voltage potential. Rapid signal propagation.
