Study of Imbibition using dried seeds/raisins.   Aim:  To study the imbibition using seeds or raisins.   Requirements:  Water, beaker, dry seeds or raisins, etc.   Principle:  Imbibition is the adsorption of water or any other solvent without forming a solution.  The different hydrophilic substances present in plant cells or cell walls, imbibe water.  Figure by using raisins  Procedure: Take some dry seeds or raisins in a beaker or Petri dish or bowl.  Add an ample amount of water to it.  Keep the set up for a few hours and observe the change in Observation: The seeds or raisins kept or soaked in water show change in their volume showing the swollen structure and seed coat/raisins shows softening.   Conclusion:  When seeds are immersed in water, they swell due to imbibition.  This swelling up causes a temporary increase in the volume of the cell.  transported and does not
