Is solute potential same as osmotic potential?
yep!
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
What do we call 2 solutions that have the same water potential?
Iso-osmotic or isosmotic
What are the factors which affect rate of diffusion?
the factors which affect rate of diffusion is the factors that mixing one substance to another.
What is the different between turgor pressure and diffusion?
The difference of turgor pressure and diffusion is that turgor pressure is an osmotic pressure exerted by the contents of a plant cell against its cell wall; while diffusion is a movement of molecules from an area higher concentration to an area lower concentration.
What is diffusion in substances?
Concentration increases the number of molecules to pass through, hence the result.
How does humidity affect the water potential?
As you decrease humidity, I believe the water potential of the environment also decreases. Conversely, if you increase the humidity, the water potential increases. An example can be found in water movement of leaves. As the humidity increases, the rate of diffusion goes down because water moves from areas of high water potential to low water potential. Thus, as the humidity goes down, the rate of diffusion of water from leaves to the environment increases because water potential of the environment is lower (more negative) than the leaf's, so water flows out of the leaf.
What is diffusion pressure deficit?
Water potential of protoplasm of the cell is equal but opposite in sign to the diffusion pressure deficit(DPD) or suction pressure(SP).Thus DPD of an osmotic system is the water potential in terms of energy.DPD is expressed in positive value.
What role does diffusion play in helping a plant take in water?
Water from the soil diffuse inside due to osmotic potential of cell sap of root hair and onward

Is solute potential same as osmotic potential?
yep!
Is facilitated diffusion limited by osmotic pressure?
Yes, it is!
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 is matric potential?
Matric potential is the sum of: Osmotic Potential(φs) + Hydrostatic Pressure(φp). Matric potential useful because there are some situations where it is difficult to distinguish between the measurements of Osmotic Potential(φs) and Hydrostatic Pressure(φp).
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
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).
