今天還是為大家分享生物知識，兼職芒果要説的是osmosis
Osmosis refers to the net movement of water from high water potential to low water potential
movement of water will occur regardless of water potential gradient
hence the key is the NET movement
water potential = solute concentration + pressure applied
reaching zero/ equal water potential does not mean both solution must have the same concentration, since concentration is determined by the amount of solute, not water potential 24Please respect copyright.ＰＥＮＡＮＡcrrYzZuvcR
Suppose a solution has reach zero water potential, there is a chance that water keeps entering the solution by osmosis, but something (e.g. cell wall ) has created a pressure, pushing the excess amount of water outside the cell, such that there is no net movement of water moving into the solution by osmosis.
Or in other words, the solute concentration = pressure applied
