Title: I am not understanding how water passes through root hair cells (read details) ? Post by: sam19ky on Nov 28, 2016 Why do people say that water moves into the cell because the water concentration of the cell sap is low ? the cell sap is surrounded by a membrane so if any water moves into the cell it must be because the concentration of water in the cytoplasm is lower than the surroundings. I am thinking that water from the cytoplasm moves into the cell sap solution and as a result , the concentration of water in the cytoplasm decreases so water moves in from the surroundings.

Post by: Othello2 on Nov 30, 2016 So the rule is that water follows solutes, your body always wants to even things out and make the solution isotonic. If there is too much salt in the cell then water will move into the cell. If you are dehydrated (so there is more salt and ions outside the cell) then the water will move out of the cell to try and make it even.
