Imbibition is a type of diffusion by which movement of water takes place along a diffusion gradient. Due to this process certain dried and half-dried matters absorb water. Such substances (e.g., fibres, wood pieces, proteins and sponges) are called adsorbants. An adsorbant is required for the imbibition to occur. The cell wall and the protoplasm […]
