The osmotic potential of a cell is -5 bars then what would be its osmotic pressure value?

To calculate the osmotic pressure (Π) from the osmotic potential (Ψ) in the context of plant cells or solutions, you can use the following relationship:

Π = -Ψ

In this case, you mentioned that the osmotic potential (Ψ) is -5 bars. To find the osmotic pressure, simply substitute this value into the equation:

Π = -(-5) = 5 bars

So, if the osmotic potential of a cell is -5 bars, the osmotic pressure value would be 5 bars. Osmotic pressure is expressed in the same units as osmotic potential, but with the opposite sign.
