Hello everyone. And in today's video we have the following problem If soil water potential is low, water can possibly flow from plants into the soil to avoid this. What adaptation strategy do plants use? And this is nothing more than a problem on diffusion. And I want you to recall what diffusion means for a plant diffusion is nothing more than a movement of water from an area as we can see of low concentration of salutes to an area of high concentration of solute as represented by these red dots. Now, what is happening here is that the water potential is low because the solid concentration within the plant is lower than outside the plant, causing water to move out to prevent this water is going to store very high concentration of salutes within its roots. And what this is going to do is that it's going to flip the gradient. So now the concentration within the roots is going to be higher than outside the roots. Which is going to cause water to still go into the roots, even though this water potential is low through diffusion. And so that is why. And to choice deep to store high concentration of solute is correct because it aids that diffusion process. So thank you very much for sticking around until the end of this video. I really hope it helped
