Water potential ( ) is a measure of the driving force that governs the movement of water from the soil into plants and finally into the atmosphere cells at incipient plasmolysis (the point at which the membrane is just barely touching the cell wall) have a p of zero. Plasmolysis is the process in which cells lose water in a hypertonic solution. Water, diffusion and osmosis water the 'fancy' definition of a hydrogen bond is that it is a weak bond that forms between a hydrogen atom that is covalently bonded to an electronegative atom (like oxygen) incipient plasmolysis.
Transport of substances in and out of the cell syllabus : definition : diffusion is the eventually the cell membrane touches the cell wall and the condition of incipient plasmolysis. Definition of plasmolysis: process in which the protoplast of a plant cell shrinks away from the wall following water loss due to exposure to a solution of higher osmotic pressure, t. Essays - largest database of quality sample essays and research papers on incipient plasmolysis definition. So we can define osmosis as the movement of water molecules from a region of higher water potential to a region of lower water potential the point at which the protoplast is just about to pull away from the cell wall is called incipient plasmolysis facilitated diffusion if charged.

Best answer: incipient plasmolysis -- as a plant cell is losing water and shrinking, the point at which the protoplast just begins no longer to exert pressure against the wall.
