Passage of particles or water through the semi-permeable membrane is referred to as:

• Imbibition is a type of diffusion where the water is absorbed by the solid particles, causing an enormous increase in volume.
• A biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem.
