Water potential of pure water is zero . In simple term water potential is a thirst of water of a cell. Water will always flow from low water potential to high water potential. Hope it clarifies confused ones.

Osmosis is a process of movement of solvents through a semi-permeable membrane from a region of lower solute concentration to higher solute concentration.
Water molecules move from lower to higher concentration... where solute concentration is higher then water is lower in that solution and water moves from lower to higher conversation
Thank you so much Ambarish for your appreciation. We are glad that you understood the concept. For more videos, please visit our website - dontmemorise.com/
In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute. So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides.
@@manikuddin2540 just read this line 5 times and try to understand! "Movement of water from lower concentration to upper concentration through semi permeable membrane." OR "Movement of water from downhill to uphill through semi permeable membrane." HOPE IT HELPS!! ☺️
@Idkykikyk pretty sure they are saying that in an area with a higher solute, there is less water. The less solute, the more water. So the water in the areas of low solute move to areas of high solute. ( at least I hope so)
Actually water(solvent moves from low to high But then I noticed that it's high water conc(low conc) to low water conc(high conc) which is practically the same! Ok...
Water moves from a region of high water potential (which means high water concentration or low solute concentration) to a region of low water potential (low water concentration or high solute concentration).

I think osmosis doesn't need energy to occur It's reverse osmosis(RO) that needs energy. I love this channel, here I just want to make a small correction.
@srikanth v water moves from a region of high conc. of solute molecules to region of low con.c of solute molecules. Reverse only happen under active transport. whatsapp me we engage more on +254792870152
I understand that the water wants to go from a higher concentration to an equal concentration, and I understand that the effect is called osmosis, but why does water want to do that? Is it the fact that water is diamagnetic? Is it that the water is attracted to the sugar on the other side of the membrane? Is it both?
Actually water(solvent moves from low to high But then I noticed that it's high water conc(low conc) to low water conc(high conc) which is practically the same! Ok...
Water molecules are very cooperative with other water molecules and also like that all water molecules remain together so where water molecules are in lower concentration then water molecules move to high concentration and this movement of water molecules is called osmosis... basically osmosis is transportation of water from lower to higher
OK I think I figured out a mechanism for osmosis. Sal's explanation is kind of correct but doesn't quite express it right. The gist of it is that there is a net momentum vector for all the matter in the system that sits on the solute-solvent mixture side of the membrane. If you break the system down into two masses, the mass of water, and the mass of solute, we see that the mass of water's (solvent's) center of momentum movement is directly in the middle of the system over the membrane. However, when we look at the mass of solute's center of momentum, we see that it's in the middle of only the solute-solvent side. When you take the average of these two momentum vectors you get a net momentum vector that has a center somewhere between the two in physical space, so the tendency overall is for the water to move in the direction of the solute-solvent side toward the center of mass of the system. Another way to think of it is that the barrier imparts energy to the system only on the side in which it is capable of deflecting matter (solute side). The Brownian motion of the molecules is the driving energy of the movement of molecules in the system. Where does the energy come from from the Brownian motion? Well, perhaps there is some internal energy at the subatomic/nuclear level, but I suspect it's more driven by the addition of heat from the environment and the transfer of kinetic energy to the particles from the barrier and walls. If a molecule hits the membrane, it is accelerated in the opposite direction. Energy is imparted to the molecule from the wall, and the wall gains energy from the particle. With each exchange, some kinetic energy is lost due to friction. Because the membrane is, on net, only interacting with the solute particles, any kinetic energy that the solute particles lose to the membrane barrier is lost only in that side of the system, but not the other half. This would imply the overall kinetic energy of the solute-solvent system is less than the pure-solvent side, which would obviously lower the water pressure and thus move water, on net, into the solute-solvent mixture side. But, you might ask, osmosis is powerful enough, apparently, to work against gravity. This requires work, so energy LOSS doesn't seem to really explain how it can do work. Well, like I said, the Brownian motion of the particles is constant overall, so whatever inputs to the Brownian motion of the particles are, it must be the energy into these inputs that osmotic energy is driven by. It must be the case that the heat of the environment is going into one side of the system at a higher right than the other. I suppose that the solution must have the same temperature throughout on both sides of the membrane (does it? I suppose this could be measured). The order of energy seems to be: heat from environment --> Brownian motion of liquid particles (Kinetic Energy) --> energy lost to membrane barrier The energy lost to the barrier must be small compared to the increased input from the environment, otherwise you wouldn't be able to do work like elevate the solution against gravity. I would therefore speculate that the rate of heat intake in the system is greater on the solute-solvent side, because for the Brownian motion to remain constant, one needs an increased amount of energy to compensate for the energy lost at the membrane. So that's my hypothesis about osmotic mechanism. Any thoughts? The next question I have is: if this description is correct, does it imply that the total osmotic pressure is linked (proportional to) to the surface area of the membrane, or that the surface area of the membrane merely affects the rate of osmosis overall? Intuition at first tells me that the increased surface area of a membrane should increase the osmotic pressure overall, however as far as I know, the osmotic pressure is directly proportional to the solute concentration only, not the membrane surface area. This may imply that the surface area of the membrane only affects the rate of exchange, but not the overall osmotic pressure. This could be tested empirically by simply having two separate identical systems in terms of water mass, solute concentration on one side, and varying only the surface area of the membrane, and then measuring (1) what the rate of water movement is, and (2) what the overall end result is at equilibrium. If the rate varies but the end result is the same, then the membrane surface area doesn't affect the osmotic pressure. If the end result varies, then the osmotic pressure is proportional to the surface area of the membrane. As a secondary experiment, you could measure the temperature of the fluids and the rate of heat exchange on both sides of the membrane.
The pressure that moves water in and out of cells is called water potential. Pure water has a high water potential and so water is very likely to move into cells if they have water around them.

Hey always we are concern with solvent not the solute 😂😂
Solute will not pass through membrane
fuck off
Water moves from a region of high water potential (which means high water concentration or low solute concentration) to a region of low water potential (low water concentration or high solute concentration).
Tq...😁I literally confused...

tank u so much
Mam why molecules are able to move on their own in a gas or a liquid
They are not packed tightly as in solids
1. Water Molecules are dispersed in Liquid form.
2. In Liquid Form they have High Kinetic Energy then solid form.
Water molecules are very cooperative with other water molecules and also like that all water molecules remain together so where water molecules are in lower concentration then water molecules move to high concentration and this movement of water molecules is called osmosis... basically osmosis is transportation of water from lower to higher

Then what do we call the movement of water from low concentration to high concentration with the help of membrane??
Reverse Osmosis, and that also requires energy from respiration like active transport.
