Osmosis is the movement of water molecules from their region of higher concentration (dilute solution or with a lower solute concentration) to their region of lower concentration (concentrated solution or with a higher solute concentration) through a semi permeable membrane.
(ii) Cell sap acts like sugar solution and cell membrane acts like parchment paper.
(iii) The control setup is shown below:
