Plasmolysis Definition & Meaning - Merriam-Webster

WebNov 18, 2016 · Plasmolysis Definition. Plasmolysis is when plant cells lose water after being placed in a solution that has a higher concentration of solutes than the cell does. This is … WebThis condition is known as ‘incipient plasmolysis’. At incipient plasmolysis, the cell wall exerts no pressure on the cell contents (i.e. pressure potential is zero). Therefore, the water potential in the cell is equal to the solute potential. Water potential (Ψ w) = Solute potential (Ψ s) + Pressure potential (Ψ p).
