Water potential and its components for CUET PG<\/h2>\n
A plant physiologist measured the osmotic potential and pressure potential of a leaf cell as -0.5 MPa and 0.2 MPa, respectively. Calculate the water potential of the leaf cell.<\/p>\n
The water potential (\u03a8<\/em>w<\/sub>) of a cell is a measure of its tendency to gain or lose water. It is calculated using the formula:\u03a8w<\/sub>= \u03a8s<\/sub>+ \u03a8p<\/sub><\/code>, where\u03a8<\/em>s<\/sub>is the osmotic potential (also known as solute potential) and\u03a8<\/em>p<\/sub>is the pressure potential.<\/p>\nGiven values are:\u03a8<\/em>s<\/sub>= -0.5 MPa and\u03a8<\/em>p<\/sub>= 0.2 MPa. Substituting these values into the formula:<\/p>\n\u03a8w<\/sub>= -0.5 MPa + 0.2 MPa = -0.3 MPa<\/code><\/p>\nThe water potential of the leaf cell is -0.3 MPa. A negative water potential indicates that the cell has a lower tendency to gain water and a higher tendency to lose water.<\/p>\n
Key points:<\/strong><\/p>\n\n- The osmotic potential (\u03a8<\/em>s<\/sub>) is a measure of the effect of solutes on water potential.<\/li>\n
