WebWater potential is typically expressed in potential energy per unit volume and very often is represented by the Greek letter ψ. Water potential integrates a variety of different potential … WebWater potential refers to the tendency of water to flow or move from one place to another as a result of various factors such as gravity, osmosis, mechanical pressure, capillary action, and so on. The seed, as well as semi-permeable or porous material like wood or colloid, absorb water from the soil during the imbibition process.
WebThis water loss causes a decrease of the protoplast cell volume and eventually leads to plasmolysis (the separation of the plasma membrane from the cell wall).
