The term water potential is also used for ________ pressure.

Water potential is the modern term used to describe the chemical potential of water. It is numerically equal to the Diffusion Pressure Deficit (DPD), which is also known as suction pressure, but with a negative sign.

While osmotic pressure corresponds to osmotic potential and turgor pressure corresponds to pressure potential, suction pressure (DPD) corresponds to the overall water potential of the cell.

Answer: suction
